TZM alloy (High Temperature Alloy) is the prime alloy of molybdenum. It contains 99.2% min. to 99.5% max. of Mo, 0.50% Ti and 0.08% Zr with a trace of C for carbide formations. TZM offers twice the strength of pure moly at temperatures over 1300°C. The recrystallization temperature of TZM is approximately 250°C higher than moly and it offers better weldability.
The finer grain structure of TZM and the formation of TiC and ZrC in the grain boundaries of the moly inhibit grain growth and the related failure of the base metal as a result of fractures along the grain boundaries. This also gives it better properties for welding. TZM costs approximately 25% more than pure molybdenum and costs only about 5-10% more to machine. For high strength applications such as rocket nozzles, furnace structural components, and forging dies, it can be well worth the cost differential.
TZM is available in sheet and rod form in basically the same size range as moly with the exception of thin foil. Rembar is experienced in the fabrication of TZM. Refer to the separate TZM sheet.
TZM and MoLa Alloys have higher recrystallization temperature, high heat resistance and better creep resistance over pure Mo.
