market traded market prices have declined grade gr 5

Chinese titanium sponge titanium temporarily stable overall market decline in value

Transient stability of domestic titanium City recently . grade 2 titanium wire‍ International Titanium seeds, ilmenite European market demand continues to slump , weak turnover , while the North American market is relatively stable ilmenite , the U.S. and Canadian producers have said that at present , ilmenite trading activity is relatively stable, market supply and demand balance , there is not much changes , the current price is relatively strong, think short term, it will not be much fluctuation .

Domestic titanium seeds, titanium sponge recent decline in value caused widespread concern of market participants . Currently , the price of titanium sponge has been way down, 0 titanium sponge by last month 's price 65000-70000 yuan / ton , has been falling now 62000-64000 yuan / ton, the market reflects the business and even now traded titanium sponge in fact, the price is lower than the current price , 0 titanium medical grade titanium alloy‍ sponge in the market at 60,000 , 60,000 or even less than the price could get arrived.

However, according to understand that the titanium sponge prices have dropped a lot, because of the bearish outlook , buyers are currently low market inquiry , but manufacturers insist on quoted market prices remain unchanged , at present , the domestic part of the titanium sponge manufacturers adhere to market price 0 65,000 yuan / ton , a market price of 64,000 yuan / ton, but the market traded market prices have declined , although , at present , the mainstream transaction prices have fallen to 0 62,000 yuan / ton , about a 60,000 yuan / ton.

The market outlook , there are manufacturers that titanium tetrachloride , titanium tetrachloride possibility outlook fell sharply small. Because the market oversupply situation has improved , the market supply is not much, the price would no longer fall down .

Bottomed titanium tetrachloride , titanium sponge still not keep up with market demand , according to the manufacturers , the current decline in the price of titanium sponge , or keep up with demand for its market , buyers inquiry prices are low, manufacturers profit is limited, the price is too low, can not hold stocks , the market volume is also not much of titanium sponge manufacturers are engaged in a tug of war with the market , and with the arrival of the end of titanium sponge market demand continues to cool , and manufacturers need capital returns , reduce inventory , titanium wire‍ market price or to compromise , come down .

Ilmenite current situation is relatively stable, Shanghai spot aluminum price of 16100-16140 yuan / ton, was up 80 yuan , China also reported up through the spot price of aluminum , ferro-titanium raw material prices are currently strong, though still insufficient market demand , but by the cost support, the market is still relatively stable, the recent market prices would not be a substantial adjustment , will remain stable.

And the recent poor weather conditions , the domestic titanium ore market tensions have emerged , Panzhihua regional market demand, prices will strongly manufacturers , market participants have predicted the subsequent market prices will rise , but the short term , due to the recent market transactions downstream titanium dioxide not very good, there is a certain decline in market confidence , yet the opportunity to raise prices , medical titanium plate‍  ore market will stabilize over time.‍

Faced with increasingly hot iron ore market titanium bar rod

Russia " IRC " titanium 260,000 tons annual output of 65%

Australia 's third largest iron ore company titanium grade 7‍ FMG , the Russian iron ore companies IRC also hope to find in China making the rich dream.

GARINSKOYE planned capacity of 4.6 million tons of iron concentrate , 2012 to 2013, the project started in 2015 officially put into operation .

grade gr 1 Memory alloy is an atomic arrangement

Memory alloys for artificial heart

Memory alloy is an atomic arrangement is very rules into martensite is less than 0.5% by volume of phase change alloy . This alloy will be deformed under an external force when the external force is removed, under certain temperature conditions , can restore the original shape. Because it has more than a million times to restore function, so called " memory alloys ." Of course it is not like the human brain thinking and memory , more accurately should be called " shape memory alloys ." In addition, the memory alloy also has a non-magnetic, wear and corrosion , non-toxic advantages, titanium gr 5‍ so widely used. Scientists have now discovered dozens of different memory alloys , such as titanium - nickel alloy, gold - cadmium alloy, copper - zinc alloy.

What is memory alloy 1870s , the world there is a materials science with alloy " memory" shape function . Memory is a rather special alloy metal bars , it can easily be bent , we put it in the container of hot water aquarium , metal strips rushed forward ; put it into cold water , the metal strip is restored the status quo. Container of cold water in the aquarium , the stretch of a spring , when the spring into the hot water , springs and automatically folded up . Cold water in the spring to restore its original state , while in hot water , it will shrink , spring can be an unlimited number of stretching and shrinking , shrinking again opened. The memory consists of an intelligent made ​​of metal , the microstructure of which has two relatively stable at high temperatures of the alloy can be turned into any shape you want, the alloy at lower temperatures can be stretched , but if it is reheated , it will remember its original shape , and change back. This material is called memory metal (memory metal). It is mainly a nickel titanium material. For example , a helical superalloy, after high temperature annealing , which is in the shape of a spiral state. At room temperature , that is forced to use a lot of effort to straighten it , but as long as it is heated to a certain " abnormal temperature ," which seemed to root alloy remembered something, now restored to its original helical shape . How is this going ? Did alloy also has a kind of human memory ? Original not the case ! It's just the use of certain alloys law changes the crystal structure in the titanium tube‍ solid state with temperature only. For example , a nickel - titanium alloy 40oC 40oC above and below the crystal structure is different, but the temperature change in the vertical 40oC , will be contracted or expanded metal , such that its shape is changed . Here , 40oC is a nickel - titanium shape memory alloy "abnormal temperature ." Various alloys have their own perverted temperature. Abnormal high temperature superalloys above that . At high temperatures it is spirally formed in a stable state . At room temperature when it forcibly straightened, it is in an unstable state , so long as it is heated to a temperature of metamorphosis , it is immediately restored to the spiral shape of the original is in a stable state . Classification and application of shape memory alloy can be divided into three types: ( 1 ) one-way shape memory alloy memory effect deformation at low temperature before heating the deformed shape recoverability , which exists only in the heating process of shape memory One way is called memory effect . ( 2 ) Two-way memory effect of certain alloys with shape recovery temperature heating , cooling can restore the shape of the low temperature phase , called the two-way memory effect. ( 3 ) recovery throughout the high-temperature phase shape memory effect heating , cooling into the same shape and the shape of the opposite orientation of the low-temperature phase , called the whole memory effect. Three kinds of memory effect is shown below. Has been successfully developed TiNi shape memory alloy based shape memory alloys, copper-based shape memory alloys , iron-based shape memory alloys. The earliest reports of the shape memory effect and Read by Chang et al made ​​in 1952 . They observed Au-Cd alloy reversible phase transformation . Later in the Cu-Zn alloys also found the same phenomenon, but did not attract widespread attention . Until 1962 , Buehler and his collaborators observed with macroscopic shape memory effects such as changes in the atomic ratio of TiNi alloy , it attracted the attention of materials science and industry . By the early 1970s , CuZn, CuZnAl, CuAlNi also found in other alloys with shape memory effect martensitic transformation related . For decades, research on shape memory alloy has gradually become an important issue of international conferences and phase change materials conferences , and has held a number of symposia , and constantly enrich and improve the martensitic transformation theory . In theory deepening , while the application of shape memory alloys have also made considerable progress, its scope of application involves many areas of mechanical , electronic, chemical , aerospace , energy and medical. Specific applications of shape memory alloys below. Industrial applications: ( 1 ) the use of one-way shape memory effect of a one-way shape recovery . Such as pipe fittings, antenna , rings and so on. ( 2 ) extrinsic two-way memory recovery. Namely the use of one-way shape memory effect and lifting to do with the temperature outside help repeated actions, such as heat-sensitive components, robots, terminals , etc. ( 3 ) intrinsic two-way memory recovery. Namely the use of two-way memory effect with temperature elevating do repeated actions, such as heat engines , thermal components. But such applications faster memory decay , poor reliability , not commonly used. ( 4 ) ultra- flexible application . titanium rings Such as springs , terminal, eyeglass frames and so on. Medical Applications : biocompatibility TiNi alloy good use of its shape memory effect and superelasticity medical instances considerable . If the filter thrombosis , spinal orthopedic rods, tooth orthopedic wire, cerebral aneurysm clips, plates , intramedullary nail , artificial joints, contraceptive devices , cardiac repair components, artificial kidneys using a micro- pumps. Tech applications Outlook: The 20th century was the era of mechanical and electrical science . Sensing - IC - driving is the most typical mechanical and electronic control systems, but the complexity and huge . Shape memory materials both sensing and driven dual function , the control system can achieve miniaturization and intelligent robots such as holograms , ultra- millimeter micro robots. The 21st century will be the era of e- learning materials . Action shape memory alloy robot addition to temperature conditions without any environmental impact is expected in high-tech fields reactors, accelerators , space laboratories flourish. Memory alloy spoke alloys, of course, talk about the most interesting alloys - memory alloy . Metal has a memory , an accidental discovery : the early 1960s , a research team from the U.S. Navy led to some of the warehouse nitinol wire experiments , they found that these alloy wire winding , very easy to use , so he took these alloy wire a root straightened. During the test , a strange phenomenon , they found that when the temperature rose to a certain value , which has been straightened nitinol wire suddenly restored to its original state bent , they are good at observing the heart, and repeated done several tests , the results have confirmed these filaments do ? "memory ." The discovery of Naval Research , and aroused great interest in the scientific community , a large number of scientists have conducted in-depth research . Found that zinc alloy , copper-aluminum -nickel alloy , copper-molybdenum -nickel alloy , zinc alloy, copper and gold also have this strange ability . It may be in a certain range , according to the need to change the shape of these alloys to a particular temperature, they automatically return to their original shape , and this " change - recovery " may be repeated several times , regardless of how changes they always remember the shape of his own time , to this temperature , it is no less to the prototype reproduction. It is called the shape memory effect of this phenomenon , the metal having such a shape memory effect is called a shape memory alloy , referred to as memory alloy . Why are these alloys can have such a shape memory effect ? How they remember their original shape ? With the general theory of metallic bonds , free electron theory is difficult to explain the effect of this memory alloy . Memory alloy under certain temperature conditions can be restored to original shape for sports extranuclear - movement with temperature changes , provides an excellent example. It is due to the formation of the alloy at high temperature of the liquid metal melt each other , titanium wire price‍ since the structure of the liquid metal element rejection , resulting in the structure of another metal element and the structure of each element of this element uniform solidification , its microstructure is ordered different types of structure element proportional to the electromagnetic force is the main object of the alloy constituting the cohesion . The electromagnetic force is formed by the valence and electronic operation of the electronic operating rate changes with temperature , so the electromagnetic force ( size, direction , action point ) is also inside the object temperature conditions. The resulting internal forces of metal objects with temperature changes , but these changes within a small range of temperature difference is not obvious , only performance only in the larger temperature changes ( several hundred degrees C) . Force in the general metal , can be plastically deformed as a wire is bent , the bending portion , the electromagnetic force by the external disturbance , resulting in operation of an electromagnetic plane and force electrons to the valence micro adjustment , a plastic deformation completed . Due to the different types of memory alloy structural element uniform blending with each other , despite the different size of the structure element tall, electromagnetic force , but each has its own price and speed up the operation , under certain temperature conditions adjacent peace and quiet . After the external force , the electromagnetic force of the external disturbance , and the valence electrons run to the plane of trace angle adjustment , the object is plastically deformed , in this plastic deformation , the price and the adjustment operation of the electronic part is not stretched . When the rate of change of temperature change with current prices and electrons when the temperature returns to the refreshing phase of development (transition temperature ) conditions , and does not stretch the valence electrons immediately run back to the time rate of change along the electromagnetic force , the adjacent structural element of price and running are also adjusted accordingly , the entire stretch back to the original state , so the whole object also return to the original state. This is the memory of the process memory alloy . In fact, the memory metal has long been found : a straight wire bent to a right angle (90 °), a release , it is necessary to restore it to form an angle larger than 90 ° . Put a bent wire straightening , it must fold to over 180 ° and then released, so that it can just return to the straight state, which is the Chinese idiom spoken overkill. There is a better memory alloy spring , ( talking about here is a steel spring , steel is an iron -carbon alloy ) spring firmly remember their shape , force a withdrawal , immediately return to their original appearance, only a wide temperature memory spring , so there is not a specific memory alloys transition temperature, which has some special functions . With the memory alloy deformation function at a particular temperature , the temperature can produce a variety of devices, the temperature control circuit can be produced , thermostatic door , temperature of the pipe connection . People have made ​​use of automatic memory alloy fire hydrant - fire temperature, memory alloy deformation, so that the valve opens, water spray fire. Making a connection to connect the mechanical parts , pipes , air refueling aircraft interface is the use of a shape memory alloy - two oil pipes tacking , the use of electric heating temperature change , the interface memory alloy deformation, so that the interface tight dripping ( oil ) does not leak . Making the area of ​​several hundred square meters of space station antenna from Fair - first made large parabolic antennas or planar , folded into a ball on the ground, with the spacecraft to the space , the temperature changes , since the development of a large area and the original shape. Memory alloys have been to dozens of current development in the aerospace, military, industrial, agricultural , medical and titanium target other fields have a purpose , and the development trend is very impressive, it is grand plans for the benefit of mankind.

Shape memory alloys have been found so far a dozen memory alloy system. Include Au-Cd, Ag-Cd, Cu-Zn, Cu-Zn-Al, Cu-Zn-Sn, Cu-Zn-Si, Cu-Sn, Cu-Zn-Ga, In-Ti, Au-Cu-Zn , NiAl, Fe-Pt, Ti-Ni, Ti-Ni-Pd, Ti-Nb, U-Nb and Fe-Mn-Si , etc.

Application memory alloy application memory alloy is widely used. For example, the fastening pin machinery, fittings, fire alarm on electronic equipment , connectors , integrated circuits, soldering , artificial heart valves for medical , chiropractic stick, skull repair surgery, orthopedic and oral teeth mandible repair surgery. It will also play a magical performance in a communications satellite , color TV , temperature controllers and toys , etc., will also be new material on all fronts , modern maritime, aviation , aerospace , transportation , textile and so on.

Memory alloy pipe has been used in combination with automatic control , the sleeve may be made ​​of shape memory alloy instead of welding , is in the low temperature expansion of the tube to approximately 4% of the full , titanium gr 5‍ a socket assembly with a heated , shrinkage of the sleeve restore the prototype , form a tight engagement . U.S. Navy aircraft hydraulic system uses a 100,000 such joints, oil spills and damage over the years never happened . Ship and submarine oil pipeline damage , repair it with a shape memory alloy fittings, very convenient. In some parts of the inconvenience of construction , the pin made ​​of shape memory alloy , into the hole is heated to separate the trailing end automatically curl to form single assembly .

Memory alloy is particularly suitable for thermo-mechanical and automatic temperature control , automatic opening and closing has made ​​room arm can open the windows are in the sunshine during the day , automatically turns off when the night temperature drops. Memory alloy heat engine designs are also a lot that they can be in with a low temperature difference between the two media work , so as to take advantage of industrial cooling water , nuclear reactor heat, ocean thermal and solar power opened up new avenues . Now the problem is widespread efficiency is not high, only 4 % to 6% , to be further improved .

Memory alloys in medical applications is also very compelling. E.g., the bone with the bone plate , not only can two fixing broken bones , and the recovery of the original shape of the compression force is generated , forcing the broken bones are joined together . After straightening teeth using dental wire , long clip ligation of cerebral aneurysms and vas deferens , with the support plate straightening the spine , titanium grade 5‍ are implanted in the human body temperature by the action starts, thrombus filter is also a new product memory alloy . After being straightened filter implanted vein , will be gradually restored into a network , thereby preventing clot 95% flow to the heart and lungs.

Artificial heart is a more complex structure of the organ , muscle fibers of the elastic memory alloy thin film made ​​of ventricular cooperate to mimic ventricular contraction . Now water is pumped been successful.

Since memory alloy is a " life has alloy " , use it at a certain temperature changes shape , you can design all kinds of self-control devices , its use is expanding . The first application of shape memory alloy pipe fittings in and fasteners . A shape memory alloy is processed into an outer diameter smaller than the internal diameter of the pipe to be connected to the casing 4% , at liquid nitrogen temperature and then expanding the sleeve diameter of about 8% , this will be removed from the cannula assembly when the liquid nitrogen , the desire inserted from both ends of the tube connection . When the temperature was raised to room temperature , i.e., the sleeve forming a holding seal shrinkage . This connection can be in close contact with anti-leakage , far better than welding , especially suitable for aviation, aerospace , nuclear industry and submarine pipelines and other dangerous situations. The most promising application memory alloys in aerospace technology . July 20, 1969 , "Apollo" 11 lunar module landed on the moon , the first human landing on the moon to achieve the dream of traveling . After the astronauts landing on the moon , on the moon a few meters in diameter placed a large hemispherical antenna for transmitting and receiving information to Earth . A few meters from a large antenna mounted on the tiny lunar module sent into space inside . Antenna that was just invented near memory alloy used. Under normal circumstances, the first predetermined requirements of good memory alloy material with a very thin , then lower the temperature to press it into a ball , bring the day to go into the lunar module . Into the lunar surface after the temperature rise in the sunlight , titanium rings‍ when it reaches the transition temperature , antennas and " mind" from their original appearance , becomes a huge domed . At present, the shape memory effect and superelasticity has been widely used in various fields of medicine and life . Thrombus filter manufacturing , spinal orthopedic rods, plates , artificial joints, women bra , artificial heart and so on. Can also be widely used in a variety of automatic regulation and control devices. Shape memory films and filaments may be the ideal material for future ultra- miniature robots and robots. Especially its light weight, high strength and corrosion resistance makes it highly popular in various fields .

grade gr 7 Titanium material found

How to distinguish a titanium frame ?

Titanium material found

Development of titanium materials: a German chemist in 1794 ( two hundred and seven years ago ) discovered this new metal element and named it titanium titanium. Named by sources from the ancient myth of the West Prince Titan ( Titan ) , titanium grade 5‍ because he believes that super-strength titanium and ultra- refractory degree , working with the great Titan with shine .

Although titanium material in the Second ○ was discovered seven years ago , but due to refining process was not easy ( titanium is very easy to combine with oxygen ) , scientists have been unable to be refined into useful substances metals. Until 1938 , DuPont developed a new way to extract , plus magnesium reduction method, the red and gold reserves in the ground ore , after chlorination, plus magnesium , restore it and become a sponge titanium, to a ninety-four three years , DuPont began producing a large number of titanium metal products.

Development of titanium frames

Titanium is a metallic chemical element , because the refining process is not easy, and less expensive titanium material production , it is only used in the early titanium aerospace science , marine science and other high-tech science and energy development . And daily necessities are to begin in 1965 applied to the titanium material .

The first titanium frame is in九八○年someone invented the " rivet -like titanium frames " titanium welding is a very difficult material, there is no better way to do early connection handling , use rivets type of way to put it nailed together. While in 1981 , the plant began outside coated with a layer of nickel titanium material to facilitate welding. An increasingly competitive market and month of the new manufacturing methods , 1982 Day MARUMAM company pioneered the first payment in full titanium metal frames around the world ; 1984 also has factories launched nickel-plated titanium frames , there is a big price difference .

Material development of titanium

1 . Full titanium : Frame in addition to the screws and plastic gloves for outside , all metal parts made ​​of titanium material .

2 . Nickel titanium package : Borders titanium material, the surface material using a nickel package , and now this frame no longer exists.

3 . Assembled Titanium: Due to the high cost of production of nickel and titanium package to update the device , it is not updated before , assembled titanium frames as the situation , but this product is dangerous because each metal has a titanium rings‍ different melting point, literally Putting it together will be very fragile. Early nickel- titanium frame package passes flattened angle , it 's not like a factory original border distribution of production so mean , so after use , nickel, and titanium -coated layer that will break out and no way to weld repair , titanium also includes assembling such a situation .

4 . Nickel-plated titanium : In order to reduce costs, make it easier on the production, but also come up with a factory nickel plated titanium . So then processed using conventional welding techniques .

How to distinguish between pure titanium frame

1 Check the weight.

2 Check magnetic reflection.

3 Check the hinge structure .

4 with a chemical reagent checked.

5 Test conductive index .

We can be a magnet placed on the table , then leaned over the frame , if it is not generating the magnetic response of titanium frames . Also check its hinge , titanium glasses are placed two plastic or metal liner in the hinge , in addition , because of different metals with different electrical conductivity , so with conductive index can be measured whether the titanium metal .

Now consumers in addition to care about aesthetics , but also pay great attention to security , such as European countries have regulations, things come into contact with human skin items ( such as glasses , watches , necklaces , etc. ) , if necessary ingredient containing nickel marked . Because the nickel whites sometimes cause skin lesions or skin cancer , so manufacturers and stores have a duty to inform .‍

DuPont titanium dioxide want to build production bases in Shandong

 The world's largest manufacturer of titanium dioxide DuPont recently disclosed that the company is negotiating with the Dongying Economic Development Zone , want to build a world-class titanium dioxide production base in the region. According to experts, one of the country 's total consumption of titanium dioxide is an important social consumption level reference mark , because titanium dioxide broad range of applications . titanium bars for sale‍ It is the paint, plastic, ink , paper, chemical , cosmetic, pharmaceutical, food and other industries indispensable to the production of raw materials, and therefore the production of titanium dioxide has attracted increasing attention in various industrial countries. Sand and general manager of DuPont Titanium Technologies Vince DuPont vice president , said: "In the Asian market , especially in China , the current and future growth in demand for titanium dioxide faster than the rest of the world Our goal is to grow in this . the process of strategically consolidate its leading position as a major global supplier of titanium dioxide . establish new plant will greatly enhance our fast-growing markets in the ability to service customers in Dongying . " It is reported that DuPont was looking fit in Asian nations titanium dioxide production site , Dongying eventually became the site into the negotiating process . DuPont is currently the world's largest manufacturer of titanium dioxide in the United States has three production plants in Mexico and China Taiwan have a manufacturing plant, a new plant will serve the plastics in China and the Asia-Pacific region in China , coatings and paper industry. Chinese titanium dioxide industry early in the 1980s had to squeeze into the international market of titanium dioxide and titanium dioxide directly affected by the international market fluctuations. According to the report estimated that in the next 2 to 3 years , the domestic titanium dioxide market capacity growth at least equivalent to the GDP growth rate , probably in more than 10% , will greatly exceed the global average. In 2005 the country is expected to titanium dioxide demand will reach 750,000 -80 million tons. Currently , a large number of small and medium domestic enterprises titanium dioxide production of low-end products, titanium round bar‍ high-end products is still mainly rely on imports , and thus " low-end surplus , melee, high vacancies fall " situation occur within the industry . DuPont reached a production capacity of 1.2 million tons , accounting for almost global total production capacity of titanium dioxide 1/4 in the high-end market is anything they want . Domestic industry leader through a series of acquisitions of Panzhihua Iron and Steel Group , Chongqing Titanium holdings owned legal person shares 5580 shares to 29.8% stake to become the largest shareholder of Chongqing Titanium , and at the end of last year will be renamed Pan Yu Titanium Chongqing Titanium . The report noted that with Mrs help companies successfully landed in China, the country is about to kick off in a battle of titanium dioxide .
