Grade 5 Titanium (Ti 6-4) is one of the most versatile titanium alloys. Typical applications include compressor blades, discs, rings for jet engines, aircraft components, pressure vessels, and rocket engine cases. Grade 5 titanium is much stronger than commercially pure titanium, with the same stiffness and most of the same thermal properties making it a great selection for demanding applications.
