| Commercially Pure Titanium. Industry Specifications: Germany Engineering: 3.7025. Germany Aerospace: 3.7024. France: T-35. UK Aerospace Specification: BS TA. 1. Features: The mechanical properties of CP titanium are influenced by small additions of oxygen and iron. By careful control of these additions, the various grades of commercially pure titanium are produced to give properties suited to different applications. TIMETAL 35A contains the lowest oxygen and iron levels, producing the most formable grade of material. It has the highest purity, lowest strength, and best room-temperature ductility and formability of the four ASTM commercially pure grades. 35A should be used where maximum formability is required such as in explosive bonding and plate type heat exchangers. It exhibits excellent corrosion resistance in highly oxidizing to mildly reducing environments, including chlorides. It has good impact properties at low temperatures. In addition, TIMETAL 35A can be easily welded, machined, cold worked, hot worked, and cast. It is nonmagnetic. Typical heat treatment for this alloy: Anneal at 700°C for 1 hour and air cool. Stress Relieve at 500°C for 30 mins and air cool. Data provided by TIMET. |
