Carpenter titanium alloy Ti 3Al-8V-6Cr-4Mo-4Zr, or Ti-3-8-6-4-4, is a beta alloy that contains large amounts of beta stabilizers (molybdenum and vanadium) and can be heat treated. The alloy is commonly known as Beta C. A specialized application for this alloy is aircraft springs. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: TI-130.
