TIMET TIMETAL® 62S Titanium Alloy (Ti-6Al-2Fe-0.1Si); Beta Forged
Categories:	Metal; Nonferrous Metal; Titanium Alloy; Beta Titanium Alloy
Material Notes:	Low Cost, Multipurpose Alloy. Tensile/toughness property data below for Beta Forged, RA material. Properties and processing characteristics equivalent to or better than TIMETAL 6-4, but with significantly higher stiffness (elastic modulus). Due to the use of iron as the beta stabilizer, the alloy has lower formulation costs than TIMETAL 6-4. Typical heat treatment for this alloy: Mill Anneal at 760°C for 1-2 hrs, air cool Data provided by TIMET.
