Mainly used in the manufacture of various beams, bulkheads, slide rails, landing gear beams in aircraft structures, aero-engine fans, compressor plates, and blades. Replacing 30 CrMnSiA structural steel with TC4 titanium alloy can reduce the weight of parts by about 30%. In general, TC4 titanium alloy with standard composition is used. For aircraft structural parts requiring welding and high fracture toughness, high-purity TC4 titanium alloy with an oxygen content of not more than 0.15% is selected.
In the West, TC4 titanium alloy fasteners strengthened by solution aging treatment are widely used instead of steel fasteners to reduce the weight of aircraft structure, especially when titanium alloy or aluminum alloy is connected with carbon fiber composite materials, due to compatibility The consideration must choose titanium alloy fasteners. TC4 titanium alloy fasteners must be formed by the hot application method, which can easily meet the requirements for the organization and streamline. The fuselage bulkhead dies forging made of TC4 titanium alloy on the American F22 fighter has a projected area of 5.53m2. On the B1B supersonic bomber, the wing support through-beam structure made of TC4ELI titanium alloy is selected. It is designed according to the principle of damage tolerance and manufactured by superplastic forming and diffusion bonding methods. Its mass reaches 5400kg.
