Titanium Grade 6

Common Name
Titanium Grade 6 MMA-5137
Ti-5Al-2.5Sn A-110AT
General Information
Ti-5Al-2.5Al has good weldability and shows stability and oxidation resistance at elevated temperatures (600 – 1000°F). Applications are forgings and sheet metal parts such as jet turbine compressor blades, ducting, and steam turbine blades. The alloy is a more difficult alloy to forge with a narrow forgeability range and greater yield loss. This alpha alloy is available in bar, billet, castings, extrustions, plate, sheet, and wire.
