TIMETAL® 685 (Ti-6Al-5Zr-0.5Mo-0.25Si) Titanium Alloy
Subcategory: Titanium Alloy; Nonferrous Metal; Alpha/Near Alpha Titanium Alloy
Material Notes: Titanium content above is calculated as the remainder and may not reflect the actual range. High-Temperature, High-Strength Creep Resistant Alloy Industry Specifications: Germany Aerospace: 3.7154. France: T-A6ZD. UK Aerospace Specifications BS TA. 43, 44. Features: TIMETAL 685 possesses excellent tensile strength and creep resistance up to 520°C. It is weldable and has good forging characteristics. The alloy may be joined by the processes normally used in the fabrication of titanium, including argon-arc, electron beam and friction welding. Material should be fully heat treated prior to welding, and also given a suitable post-weld treatment. The weld zone of material treated in this way will have similar structure and properties to the parent metal. This alloy was specifically designed for the aero-engine industry. It is nonmagnetic. Typical heat treatment for this alloy: Solution heat treatment: 1050°C for 30 mins, oil quench. Aging heat treatment: 550°C for 24 hours, air cool. Data provided by TIMET.
