Titanium alloy TA6 (Ti-5Al)
It has good welding performance and high creep strength, but its process plasticity is low, it can be deformed in a hot state, and its cutting performance is still good. It is suitable for parts and weldments that work below 400 °C.
It is mainly used to manufacture compressor components, such as forged titanium fans, compressor discs and blades, cast titanium compressor casings, intermediate casings, bearing housings, etc. The spacecraft mainly uses the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to manufacture various pressure vessels, fuel storage tanks, fasteners, instrument straps, frames and rocket shells. Artificial earth satellites, lunar modules, manned spacecraft and space shuttles also use titanium alloy plate weldments.
