TC11 titanium alloy is a widely used high-temperature titanium alloy, with a maximum service temperature of 500 ℃. It is mainly used in parts of aero-engine compressors, such as blades, discs, drums, and shafts. It can also be utilized to create castings in unique shapes. The working conditions of the products are: in the annealing state, they can be used for 500 hours below 500 ℃, 100 hours below 550 ℃, and 1000 hours below 450 ℃. In the strengthening state, they can be used for parts that work for 100 hours below 500 ℃, and parts that work at a time below 700 ℃. Similar grades are BT9(VT9) (Russia).
