Titanium screws used bike

Titanium gives the impression that "light and hard." Keen lightweight riders tend to have replaced all the screws of titanium alloy plate alloy was satisfied. Titanium give some people the wrong impression, expensive and rare, in fact, titanium is one of the more abundant on earth burial abundant element.
Only because refining alloy production cost is very high, the price was expensive.
Titanium light weight, high strength, and high corrosion resistance of materials, usually used in a special environment.
After the addition of aluminum, vanadium (Li.V) in pure titanium, the alloy strength improved significantly.

Titanium mechanical properties:
Alloy Name Tensile strength (MPa) Endurance (Mpa) Elongation (%) E (GPa)
6Al-4V Ti (TC4) 980 920 14 110

Titanium products advantages:
Light weight, far more than the strength of steel, aluminum, lightweight and can produce high-intensity parts, such as screws class does not rust, titanium rod hardly etched in the general environment.
Riding feeling good, titanium is also used in the shock absorber spring. Now the frame made of titanium are suitable for long ride. Some riders love titanium frame that sense excellent ride. But individuals vary, and some people think that comparison chrome-molybdenum steel, chrome-molybdenum steel frame shock absorption better than titanium frame, riding feeling is better (shape it and chromium molybdenum steel frame than titanium rod for sale frame and thin The stress of the tube to get the increase is also relevant). If processing technology has been further improved titanium tube, there may be riding the same sense and chromium molybdenum steel.

Titanium screws on the bike specifications and use the list (please add correct me):

titanium grade 5 Japan successfully implemented the use

Japan successfully implemented the use of 3D printing make bone graft
 Japan's Kyoto University Medical Research Division teams such as August 9 announced that it has made ​​a titanium grade 5 bone for different patients can be produced by the three-dimensional structure of the 3D printing technology, to four transplant patients with cervical disc successfully improved hand numb other symptoms.
    The researchers also try to do a part of the femur and spine skull . Kyoto University lecturer vine Chiun Kai said : "You can expect the technology used in the production of artificial bone resection due to a wide range of malignancies , such as bone , bone graft treatment , etc. It is believed that this technology is particularly beneficial to the complex three-dimensional shape of the pelvis and other bones . replication . "
    The team used 3D printing titanium grade 1 device to the patient's neck computed tomography (CT) data, layer by layer superimposed on a thin layer of titanium powder fired to produce a fully fit patients with cervical bone .
    Artificial chemical surface treatment and heat treatment , so that more patients with bone bonding . The artificial disc implant from the surgical removal of the success of improved hand numbness , difficulty walking and other symptoms .
    The transplant surgery is surgery clinical trials Affiliated Hospital of Kyoto University .

grade gr 2 Titanium pipe manufacturing existing sewer

Titanium pipe manufacturing existing sewer sewage treatment device
    According to the grade 1 titanium sheet information in September 1981 statistics, there WAO wastewater treatment unit 13 of the city is made ​​of titanium tubing. Except one, the other is under pressure temperature 175-204 ℃ and 2.4-3.4MPa be thermal regulation. Rensselaer, NY thermal conditioning apparatus at 204 ℃, the grade 4 titanium degree of oxidation of 50% water. In the United States the longest running titanium tube device is in the state of Florida boiling Lauderdale, this device has been in operation since 1972. Capacity and enable all of these dates titanium sewage sewer pipe manufacturing unit.
     In these devices, the titanium grade 5 chloride ion concentration is 500 to water 2500ppm, pH value of 4.3-5.0. So far, none of these devices are all aspects of the corrosion problems occurred.

grade titanium 1 The utilization of research to reduce

The utilization of research to reduce consumption of raw materials titanium
Due to the limited reserves titanium grade 5 of rutile, attach great importance to the development of domestic titanium ore enrichment and utilization of research. It has been investigated dozens of processes, methodologies and the small number of high titanium slag or synthetic rutile production of over ten thousand to several hundred thousand tons scale plant.
     To reduce the consumption of raw materials, realization of magnesium (or sodium) and chlorine in the recycling process in order to reduce their production costs. Meanwhile, at home titanium grade 7 bar and abroad have great attention to improve the recovery rate of these materials, and to strengthen the "three wastes" The utilization of titanium and strong recovery in the production process.
