USES of titanium alloy

Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance.In addition, titanium alloy process performance is poor, difficult cutting, in hot processing, very easy to absorb hydrogen, oxygen, nitrogen, carbon and other impurities.And wear resistance is poor, the production process is complex.Industrial production of titanium began in 1948.The need of aviation industry development makes the titanium industry develop at an average annual growth rate of about 8%.The world's annual production of titanium alloy processing materials has reached more than 40,000 tons, titanium alloy brand nearly 30 kinds.The most widely used titanium alloys are Ti-6al-4V (TC4), Ti-5al-2.5SN (TA7) and industrial pure titanium (TA1, TA2 and TA3).

Titanium alloy is mainly used in the production of aircraft engine compressor parts, followed by rockets, missiles and high-speed aircraft structures.By the mid-1960s, titanium and its alloys had been used in the general industry, making electrodes for electrolysis, condensers for power stations, heaters for petroleum refining and seawater desalination, and environmental pollution control devices.Titanium and its alloys have become corrosion-resistant structural materials.In addition, it is also used to produce hydrogen storage materials and shape memory alloys.

China began to study titanium and titanium alloys in 1956.In the mid-1960s, the industrial production of titanium began and TB2 alloy was developed.

Titanium alloy is a new important structural material used in aerospace industry. Its specific gravity, strength and service temperature are between aluminum and steel, but it has higher strength than aluminum and steel and excellent seawater corrosion resistance and ultra-low temperature performance.In 1950, the U.S. first used f-84 fighter-bombers as rear fuselage heat shield, wind shield, tail cover and other non-bearing components.Since the 1960s, the use of titanium alloy
