Molybdenum alloy TZM has higher strength, higher recrystallization temperature and better creep resistance strength, comparing with pure molybdenum. This thanks to removal of carbides and oxides. The recommended working temperature is 1000 ~ 1400 °C.
The molybdenum content in TZM is 99.2-99.5%, the content of titanium is 0.50%, the content of zirconium is 0.08%, and a little carbon. At high temperature above 1300 °C, the strength of TZM is twice as high as that of pure molybdenum. The recrystallization temperature of TZM is about 250 °C higher than that of pure molybdenum, and the weldability of TZM is better than that of pure molybdenum.
The price of TZM is about 25% higher than that of pure molybdenum, and the maching fee is about 5-10% higher than that of pure molybdenum. For high-strength applications such as rocket nozzle, furnace structure, forging die, TZM has good value.
