Titanium is stable in air at room temperature: Because titanium has small density, high strength, high temperature and low temperature resistance, corrosion resistance and other excellent properties, the density is only half of the steel and the strength is similar with steel, titanium alloy strength is higher than steel. Titanium plate made of pure titanium has the advantages of high strength, low density, good mechanical properties, good toughness and corrosion resistance. In addition, the processing performance of titanium plate is poor, the machining is difficult, in the hot processing, it is easy to absorb hydrogen, oxygen, nitrogen, carbon and other impurities. There is poor wear resistance, complex production process. The industrial production of titanium began in 1948. With the development of aviation industry, titanium industry is growing at an average annual rate of about 8%. At present, the world's annual output of titanium plate processing has reached more than 4 tons, nearly 30 kinds of brands of titanium plate. The most widely used titanium plates are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).

The following is a brief description of the main uses of titanium plates in the industrial field.

Titanium plate is mainly used in the production of aircraft engine compressor parts, followed by rockets, missiles and high-speed aircraft structural parts. In the middle of the 60s, titanium and its alloys have been applied in the general industry for the manufacture of the electrode in the electrolysis industry, the condenser of the power station, the heater for oil refining and desalination, and the 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. Titanium alloy has good heat resistance, low temperature toughness and fracture toughness, so it is widely used as aircraft engine parts and rocket, missile structure parts. Titanium alloy can also be used as fuel and oxidizer storage tank and high pressure vessel. Now titanium alloy has been used in manufacturing automatic rifles, launch tube mortar base plate and recoilless guns.

In the oil industry, it is mainly used for a variety of containers, reactors, heat exchangers, distillation tower, piping, pumps and valves.
Titanium can be used as condenser of electrode and power station and environmental pollution control device. Ti Ni shape memory alloy has been widely used in instruments and meters. In medicine, titanium can be used as an artificial bone and various appliances.

Titanium plate is one of the most important structural materials used in the aerospace industry. The specific gravity, strength and operating temperature are between aluminum and steel, but it has high specific strength, excellent corrosion resistance to seawater and ultra-low temperature. In 1950, it is the first time that the United States used titanium plate on the F-84 fighter bomber as rear fuselage insulation, wind guide cover, tail cover and other non bearing components. In 1960s, it began to use the titanium plate from the rear fuselage moved to the fuselage, to replace the structural steel frame.
