Titanium is an important structural metal. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Titanium alloys are mainly used for aircraft engine compressor components, rockets, missiles and high-speed aircraft structures. Titanium and its alloys are important corrosion-resistant structural materials, and are also used in the production of hydrogen storage materials and shape memory alloys.
The amount of titanium alloy in aeroengines generally accounts for 20% to 30% of the total weight of the structure. It is mainly used to manufacture compressor components, such as forged titanium fans, compressor discs and blades, cast titanium compressor casings, intermediate casings, Bearing housing, etc. The spacecraft mainly uses the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, structures and rocket shells.
