Titanium alloy: the main structural material for aircraft and navigation, and the proportion of advanced military aircraft titanium has significantly increased. Titanium alloy has many advantages over other metals in weight reduction of aircraft structure, adaptation to high temperature and corrosive service environments, and service life improvement of the airframe, due to its advantages of high strength of steel, low density of aluminum, and corrosion resistance. More and more attention and wide application have been paid to the selection of new generation weapon equipment structure materials all over the world, especially in the structure manufacturing of advanced fighters.
