| 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. | |
