TIMET TIMETAL® 6-2-4-6 Titanium Alloy (Ti-6Al-2Sn-4Zr-6Mo), 50% Equiaxed Alpha + Annealed
Categories:	Metal; Nonferrous Metal; Titanium Alloy; Alpha/Beta Titanium Alloy
Material Notes:	This entry has UTS, TYS, Elongation, ROA, and fatigue values specific to material in the 50% Equiaxed Alpha + Annealed (705°C/1hr/AC) condition. Other data below are typical of TIMETAL® 6-2-4-6. High-Strength, Intermediate Temperature Alloy Features: TIMETAL 6-2-4-6 is a stronger derivative of TIMETAL 6-2-4-2 offering higher strength, depth hardenability and elevated temperature properties up to 450°C. This alloy is similar in forgeability and crack sensitivity to TIMETAL 6-4. This alloy is used in intermediate compressor stages of turbine engines for disks and blades, seals, and for airframe parts. It is nonmagnetic. Data provided by TIMET.
