VT22 alloy is used in annealed and thermally hardened states. The structure of the annealed BT22 alloy is approximately equal to the amounts of the phases a and b and therefore belongs to the strongest titanium alloys in the annealed state.
Application: The alloy is designed to produce highly charged parts and structures for a long time at temperatures of 350 to 400 ° C. It produces fuselage power components, wings, stampings, system parts control, fasteners such as wing bolts.
