Titanium alloy is an alloy based on titanium with other elements added. The density of titanium alloy in 4.51 g/cubic centimeters commonly, only 60% of the steel, the specific strength of titanium alloy (strength/density) than other metal structure material, can make the unit high strength, good rigidity, light components.
Titanium alloy is mainly used to make aircraft engine compressor parts, followed by rocket, missile and high-speed aircraft structural parts. Meanwhile, titanium and titanium alloy materials gradually entered the civil field. Titanium and titanium alloy plate, pipe, tape, wire, foil, such as bread, ring processing materials and various metal compound material made of titanium products, in the medical, sports and glasses, watches, washing machine, and other areas of the consumer goods available, favored by the market, the market is very huge in the future.
China has the advantages of titanium resources, and China has the largest reserves of titanium resources in the world. According to the relevant data, China has a proven resource reserve of 870 million tons, about 60% of the world's proven reserves. Since 2010, China's titanium production has ranked first in the world. At present, more than 50 kinds of titanium alloys have been developed, nearly 30 of which are listed in the national standard. Due to the increasing demand for titanium in the civil field, China's titanium industry has developed rapidly.
At the same time, the domestic production of titanium and titanium alloy products is far from the civil market demand. Compared with foreign countries, the application technology of titanium alloy in China is relatively backward, mainly reflected in the low proportion of military titanium and the relatively narrow field of civil titanium. For example, the amount of titanium used in the f22 of the fourth-generation aircraft in the United States reached 41%(structural quality), the amount of titanium used in its f119 engine reached 40%, and the amount of titanium used in Chinese aircraft was about 3%~10%. It is also weak in basic research, less original and revolutionary titanium design and technology.
