          The aviation industry is the oldest department of the development and application of titanium and titanium alloys, aircraft and engine titanium is actually impossible to create a 2.7 Mach supersonic aircraft. The quality of each of the aircraft engine to reduce 1kg, the costs are usually saving 220-440 dollars. 1950 U.S. F84 fighter-bombers for the first time after the manufacture of industrial pure titanium body insulation panels, wind shield and tail cover non-bearing components. The United States Bo Laite. Whitney (Pratt & Whitney) in 1954 with the Ti-6Al-4V titanium alloy to create the J57 turbojet engine compressor rotor disk and blades. British Rolls-Royce (Roll-Royce) in 1954 in the Avon engine uses a Ti-6Al-4V titanium alloy. After the 1960s, the amount of titanium alloys in the engine gradually increased, mainly for the fan blades, compressor blades, plates, shaft and casing, a large number of applications of titanium alloys in aircraft structures is a matter of the mid-1960s, Prior to this small amount. Mainly used for aircraft skeleton, skin, fuselage bulkheads and landing gear.
          Titanium and its alloys, the specific strength (strength to weight ratio) is very high in the metal structure materials, its strength and steel, but its weight is only 57% of the steel. In addition, the heat resistance of titanium and its alloys is very strong, the atmosphere of 500 ° C maintains good strength and stability, short-term working temperature can even more. Aluminum at 150 ° C, stainless steel at 310 ℃, the loss of their mechanical properties. Aircraft, missiles, rockets flying at high speed, its engines and the surface temperature is quite high, aluminum has been incompetent, then the use of titanium is very appropriate. It is because of titanium and its alloys have a strength, light weight, heat resistance and excellent performance, and use it instead of other metals, not only to extend the aircraft service life, and can reduce its weight in aircraft manufacturing, which greatly to improve its flight performance. So, titanium is one of the most promising structural materials in the aviation industry and the universe industries. Titanium and its alloys in the aerospace industry is mainly used for the manufacture of aircraft engines and airframe. In general, less than Mach 2 aircraft, its engines as part of titanium and its alloys, body in general with the aluminum alloy. The Mach number is equal to the two aircraft, its engine with titanium content increases, but the body is also part of the required titanium. Greater than Mach 3.5 aircraft, engine inlet temperature is high enough, can not be used titanium alloy and required super alloys, titanium content but the body is significantly increased. Titanium and its alloys also have good low temperature performance, even at extremely low temperatures of -250 ° C, it still has a higher impact strength, high pressure anti-vibration, titanium and its alloys in rockets, missiles and spacecraft not only for the manufacture of the engine casing and structural components, and used in the manufacture of pressure vessels, such as high-pressure cylinders, cryogenic liquid fuel tanks.
