Titanium alloy processing parts manufacturer said, titanium alloy products are: plate, strip, foil, tube, rod, forging, wire, different kinds of titanium alloy properties, advantages and disadvantages are not the same, can be used for different purposes. It is mainly used to manufacture compressor components, such as forged titanium fans, compressor discs and blades, cast titanium compressor casing, intermediate casing, bearing housing, etc. Spacecraft mainly use titanium alloy high specific strength, corrosion resistance and low temperature performance to manufacture a variety of pressure vessels, fuel tanks, fasteners, instrument straps, frames and rocket housing. Man-made earth satellite, lunar module, manned spacecraft and space shuttle also use titanium plate welding pieces.

Titanium alloy products for medical use

Titanium is non-toxic, light, high strength and excellent biocompatibility, so it is an ideal metal material for medical use as human implants. Ti-6al-4v ELI alloy is still widely used in the medical field. However, vanadium and aluminum ions can be precipitated from the latter, which reduces the cellular adaptability and may cause harm to human body. This problem has long attracted extensive attention in the medical field. The United States began to develop aluminum-free, vanadium-free titanium alloy with biocompatibility as early as the mid-1980s, and used it in orthopedics. Japan, Britain and other countries have also done a lot of research work in this area and made some new progress. Japan, for example, has developed a range of α+β titanium alloys with excellent biocompatibility, Including Ti-15Zr-4Nb_4TA-0.2Pd, Ti-15Zr-4Nb-ATA-0.2Pd-0.20-0.05N, Ti-15Sn-4Nb-2Ta-0.2Pd and Ti-15Sn-4Nb-2Ta-0.2Pd-0.20, ti-15Sn-4Nb-2Ta-0.2Pd and Ti-15Sn-4Nb-2Ta-0.2Pd-0.20. The corrosion strength, fatigue strength and corrosion resistance of these alloys are better than those of Ti-6Al-4V ELI. Compared with α+β titanium alloy, β titanium alloy has higher strength levels, as well as better incision performance and toughness, making it more suitable for implantation as an implant. In the United States, five β titanium alloys have been recommended for medical use, Namely, TMZFTM (Ti-12Mo-^ Zr-2Fe), Ti-13NB-13Zr, Timetal 21SRx (Ti-15Mo-2.5NB-0.2Si), Tiadyne 1610 (Ti-16Nb-9.5Hf) and Ti-15Mo. It is estimated that ti-6Al-4V ELI alloy with high strength, low elastic modulus and excellent formability and corrosion resistance is likely to replace ti-6Al-4V ELI alloy widely used in the medical field in the near future.
