Cutting - like a punch in the desired shape punched out the hair department. Concentric shape of 
titanium, the maximum titanium grade 2 sheet cutting thickness of 3.2 mm, the maximum thickness of the irregular shape of the wool is 1.3 mm. 1.3 mm thick titanium plate below, filling the mold with the soil to create a tolerance of 0.1 mm; But for titanium wins 3.2 meters below, shall tolerances down to ± 0.025 mm. Warming will reduce the thickness of titanium cutting edge cracks. Die should titanium plate having rigidity, the upper and lower guide post to maintain the exact relative positions of the mold. When the material thickness increase, such a requirement is more urgent. Less rigid medical titanium process equipment will cause mold damage and cattle production sheet metal edge

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, grade 2 titanium wire  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 different melting point, literally Putting it together will be very fragile. Early nickel- titanium frame thin titanium sheet 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 .

Medical grade titanium alloy Marine titanium welding process

In recent years, many new ships began extensive use of titanium alloy . With the increase in the amount of titanium alloy materials , shipyard welding to enhance efficiency , product quality and stability , the need to develop some efficient titanium welding process. TA5 two kinds of titanium Shanghai Jiangnan Shipbuilding in titanium grade 4 thickness of 4mm Ti70 and 16 mm for welding object, plasma arc welding , laser welding and laser - arc hybrid welding seamless titanium tube welding three high energy density of the process carried out explore, get the excellent performance of welded joints
A plasma arc weldingPlasma arc welding is the use of plasma arc welding method as a heat source . Gas heated by the arc generated from the solution , a nozzle at high speed compressed by water , and increasing the energy density of the solution from forming a plasma arc. Its stability , heat and temperature are higher than the arc , and thus has a greater penetration power and welding speed .

Titanium bars Performance and titanium alloys are widely used in industry

titanium grade 2 sheet because of its high strength, heat resistance, corrosion resistance, widely applied in industry . Especially in aviation, aerospace , shipbuilding and other industries , mostly used in the manufacture of titanium alloy key components , its performance is good or bad usually determines the level of the product . Therefore , national research institutions to put a lot of manpower, material and financial resources to carry out its melting alloys and equipment , forming process research and development , writing papers , and many thousands of monographs . However, the study of titanium melting process with little , limited studies have limited studied. Titanium because of its high melting point, titanium grade 4 chemical activity , thermal properties between the elements of the big difference , so the smelting process of melt composition and temperature control is very difficult, and the melt composition and temperature directly determine the quality of titanium . Therefore , to identify qualitative and quantitative variation of melt composition, temperature and process parameters , alloy itself between thermal parameters have important practical significance for guiding titanium melting , smelting practice for other alloys also have important reference value

Grade titanium

Grade titanium


Titanium alloy is Ti-based alloys by adding other elements.Titanium grade 1has a high strength and density and small, good mechanical properties, good toughness and corrosion resistance. In addition, poor process performance titanium gr 2 ,  machining difficulties in thermal processing, and very easy to absorb carbon hydrogen nitrogen and other impurities. There are poor abrasion resistance, complex production process. Titanium industrial production was started in 1948.

Several major properties of titanium

Several major properties of titanium

Titanium popular range is too wide-ranging, and in the shipbuilding industry, chemical industry, manufacturing machinery parts, telecommunications equipment, carbide, etc. have a wide range of applications, titanium is also widely used in the aerospace industry, with "Space Metal" of the said.
Titanium is a very reactive metal, which is very low equilibrium potential, thermodynamic corrosion tendency in the medium is large, but in fact many of the titanium in the medium is very stable, and this is because titanium has a great affinity for oxygen, in air or oxygen-containing medium, the titanium surface layer of dense, strong adhesion, large inert oxide film to protect the titanium substrate corrosion.titanium material heat resistance, long-term use at 600 ° C or higher temperatures, but also to maintain good ductility and toughness at low temperature -196-253 ° C, to avoid the metal cold brittleness, impedance can be strong , non-magnetic, good non-toxic, heat resistance, low elastic modulus, suction performance.
Titanium in medical treatment, can be used for artificial bones and various appliances, with this titanium material shaped pieces made of titanium and titanium have a stick, it is widely used.
Do you know what the titanium isoforms is not it? The answer should not know it, and that it titanium, titanium should know what is right.
Because titanium has excellent corrosion resistance, extend equipment life, reduce maintenance frequency equipment and piping, a fundamental solution to run, run, drip, leak and other issues, save energy, increase the effective production time. The use of titanium equipment and pipelines, can reduce the cost of equipment and piping materials, lower production costs. The use of titanium, although one-time investment is large, but the overall look is economical in the long run, the actual investment is only stainless steel titanium for sale about twice titanium products due to long service life, thus reducing the updated equipment and piping costs and frequent maintenance costs, in fact, save money and reduce costs.
Titanium solve corrosion problems due to equipment and piping to avoid corrosion of equipment and piping due to contamination of the brine and caustic soda.

Titanium heart stent

Titanium heart stent

What is titanium? What is titanium heart stents? Titanium can be used as cardiac stents it? Of course, that can be used titanium alloy heart stent, made of titanium with titanium material shaped pieces to be used in medicine, incomplete treatment of the human body to get the full. Titanium heart stents after repeated research and practice, is currently the most widely used titanium alloy stent-based alloy tube, the tube body is based on the different needs and "crafted" the global done until now titanium cardiac stenting has more than 10 million cases of.
titanium supply stent has a higher compression ratio, can be placed into a smaller delivery vessel, and after the opening deformation of the stent as a whole uniform, the force is relatively uniform, the stress can widely distributed, easily cause stress concentration, so that the stent fatigue performance enhancements, and have greater radial strength. Uniform stent cell structure makes the stent may stress when the stress distribution, and effective way to avoid stress concentration, which significantly reduced the maximum stress, the stent flexibility is much better. Good mechanical performance of the new stand, and the stress distribution is more uniform, achieve the purpose of optimizing the design.
