As a “Space” metal, titanium alloy is used as engine materials, structural material, skin and a variety of pipe joints of aircrafts and rockets. The titanium content of Airbus A380 and Boeing 787 are both between 15%-20%. It is expected that in 2011, the two types of aircrafts will be produced in batch, which will drive the demands of world air titanium. China’s large aircraft, space station and Chang’e plan will use plenty of titanium. In particular, the large aircraft project will be implemented in the next few years, which will gradually increase the amount of titanium applications. 50% of titanium in the world is used in the aviation field. Comparing with more than 50% in the United States and Russia, the titanium materials applied in aviation account for less than 20% in China, so there is a broad space for future development.
