BT22 titanium alloy is generally used in the annealing state, and its semi-finished products include plates, bars, extruded profiles and forgings, which are widely used in the preparation of the main load-bearing structural parts such as the landing gear beam of the large machine, the butt frame of the fuselage, and the TC18 titanium alloy is used in the aircraft structure instead of high-strength steel or Gr5 titanium alloy, which can reduce the weight by 15%-20%.
