| Commercially Pure Titanium. Industry Specifications: USA Aerospace: AMS 4900. Germany Aerospace: 3.7055. France: T-50. UK Aerospace Specification DTD 5023, 5273. 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 65A is equivalent to ASTM Grade 3. It is a general purpose grade of commercially pure titanium that has excellent corrosion resistance in highly oxidizing to mildly reducing environments, including chlorides, and an excellent strength to weight ratio. It offers the highest ASME allowable design stresses of any commercially pure grade of titanium. 65A also has good impact properties at low temperatures. It can be satisfactorily 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. |
