is stable in the air at room temperature; because titanium has low density and high strength, the density is only half of steel and the strength is almost the same as steel, high temperature resistance and low temperature resistance, corrosion resistance and other excellent characteristics, the strength of titanium alloy is stronger than steel high. The titanium plate made of pure titanium has high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, the process performance of titanium plate is poor, and it is difficult to cut and process. During thermal processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon. Also have poor wear resistance, complex production process. The industrial production of titanium began in 1948. The needs of the development of the aviation industry make the titanium industry develop at an average annual growth rate of about 8%.
Titanium plates are mainly used to make aircraft engine compressor components, followed by structural parts of rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys had been used in general industries, such as electrodes for the electrolysis industry, condensers for power stations, heaters for petroleum refining and seawater desalination, and environmental pollution control devices. Titanium and its alloys have become a corrosion-resistant structural material. In addition, it is also used in the production of hydrogen storage materials and shape memory alloys. China began research on titanium and titanium plates in 1956; in the mid-1960s, industrial production of titanium materials began and developed into TB2 alloys.
In the petroleum industry, it is mainly used for various containers, reactors, heat exchangers, distillation towers, pipelines, pumps and valves. Titanium is used as electrodes and condensers in power stations as well as environmental pollution control devices. Titanium-nickel shape memory alloys have been widely used in instruments and meters. In medical treatment, titanium can be used as artificial bones and various appliances. Titanium is also a deoxidizer for steelmaking and a component of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints.
