Titanium is mainly used for the production of aircraft engine compressor

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 bars 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 and its alloys have become a corrosion resistant structural materials. In addition, for the production of hydrogen storage materials and shape memory alloys.
Titanium is an important new structural materials used in the aerospace industry, the proportion between the aluminum and steel, the strength and the use of temperature between, but higher than aluminum, steel strength and excellent corrosion resistance to sea water and ultra-low temperature performance. In 1950 the United States for the first time in the F-84 fighter-bombers later used as the fuselage insulation panels, wind shield, tail cover other non-load-bearing components. 1960s began using parts from titanium alloy fuselage toward the rear of the fuselage, in part, instead of structural steel bulkheads, beams, flap tracks and other important bearing components. The amount of titanium in military aircraft rapidly increased, reaching 20% to 25% by weight of the aircraft structure. Since the 1970s, civilian aircraft began extensive use of titanium alloys, such as the Boeing 747 with a capacity of 3640 kg or more of titanium. Aircraft Mach number greater than 2.5 was used in place of titanium casting to the steel, to reduce the structural weight. Again, American SR-71 high-altitude reconnaissance aircraft speed (Mach 3, altitude 26,212 meters), 93% titanium structural weight of the aircraft, known as "all-titanium" aircraft.
