Titanium 15-3-3-3 Alloy Description

Titanium 15-3-3-3 (Timetal 15-3) is a metastable beta titanium alloy that offers substantial weight reductions over other engineering materials. If used in the solution treated condition the alloyhas excellent cold formability. In the aged condition, the alloy has high strength. The alloy is acceptable for use up to 550°F (228°C).
