Titanium has a high strength and density and small, good mechanical properties, good toughness and corrosion resistance. In addition, poor process performance. Titanium tubing, 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. Require the development of the aviation industry, the titanium industry with an average annual growth rate of about 8% of the development. World titanium alloy production reached 40,000 tons, nearly 30 kinds of titanium alloys. The most widely used titanium alloy is Ti-6Al-4V, Ti-5Al-2.5Sn and commercially pure titanium.
Titanium is mainly used for the production of aircraft engine compressor components, followed by structure rockets, missiles and high-speed aircraft. The mid-1960s, titanium and its alloys have been in general industrial applications, electrodes for electrolysis industry production, power plant condensers, oil refining and desalination heater and environmental pollution control devices. Titanium wire mesh have become a corrosion resistant structural materials. In addition, for the production of hydrogen storage materials and shape memory alloys.
