TIMET TIMETAL® 367 (Ti-6Al-7Nb) Implant Grade Titanium Alloy
Categories:	Metal; Nonferrous Metal; Titanium Alloy; Alpha/Beta Titanium Alloy
Material Notes:	Medium-Strength Surgical Implant Alloy TIMETAL 367 is a dedicated, medium strength, titanium alloy for surgical implants. The alloy was developed specifically for the manufacture of femoral component items for hip prostheses. Its metallurgy is closely analogous to that of TIMETAL 6-4 but biocompatibility is improved with the replacement of vanadium by niobium. Typical heat treatment for this alloy: Anneal at 700°C for 1 hour, air cool. Data provided by TIMET.
