Need. Titanium alloy has the advantages of low density, high strength, corrosion resistance and high temperature oxidation resistance, and is widely used in aerospace, ships, automobiles, medical devices and other fields. In the aerospace field, titanium alloys are mainly used to manufacture spacecraft structural parts, engine parts, fuel tanks, combustion chambers and so on. Aerospace 35 is a research institute of China Aerospace Science and Technology Corporation, mainly engaged in the research and development of aerospace equipment and technology, so it is likely that titanium alloy materials will be used to manufacture spacecraft and related equipment.
