TZM Alloy - Titanium Zirconium Molybdenum
TZM alloy(Titanium-Zirconium-Molybdenum) (High Temperature Alloy) is a solid-solution hardened and particle-strengthened molybdenum based alloy. The development of a Mo-Ti solid solution and the fine dispersed Ti-carbides are responsible for the excellent strength properties at temperatures up to 1400°C. The recrystallization temperature of TZM (Titanium-Zirconium-Molybdenum) alloy is approximately 250°C higher than moly and it offers better weldability.
TZM alloy (Titanium-Zirconium-Molybdenum) is an alloy of 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon with the balance molybdenum. TZM (Titanium-Zirconium-Molybdenum) is manufactured by either P/M or Arc Cast technologies and is of great utility due to its high strength/high temperature applications, especially above 2000°F.
TZM Molybdenum (Titanium-Zirconium-Molybdenum) has a higher recrystallization temperature, higher strength, hardness and good ductility at room and elevated temperatures than unalloyed Molybdenum. In addition, TZM alloy (Titanium-Zirconium-Molybdenum) exhibits good thermal conductivity, low vapor pressure, good corrosion resistance and is machinable.

CTOMS stocks TZM molybdenum (Titanium-Zirconium-Molybdenum) in a variety of forms and dimensions. Below are most of the standard stock form/sizes. If you do not see the size or form of TZM Molybdenum (Titanium-Zirconium-Molybdenum) that you require, please call one of our materials experts; our sales people are very knowledgeable and can assist you. We can cut, slit, shear, or center less grind TZM Molybdenum to your exact specifications, and we also have tremendous versatility when it comes to custom sizes, packages, and unusual materials
The finer grain structure of TZM alloy (Titanium-Zirconium-Molybdenum) 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 alloy 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 molybdenum 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 alloy(Titanium-Zirconium-Molybdenum). Refer to the separate TZM sheet.
TZM molybdenum and Moly Alloys have higher recrystallization temperature, high heat resistance and better creep resistance over pure Mo.
Advantages of TZM alloy compared to pure Mo:
- better creep resistance
- higher recrystallization temperature
- better high-temperature strength
- better welding properties
TZM alloy typical areas of application:
- components for HIP, sintering and heat treatment furnaces
- metals for rotating anodes for medical diagnostics
- boats for annealing and sintering processes (temperatures up to 1400 °C)
- forming tools such as hot runner nozzles for plastic injection moulding
- moulds for light-alloy casting
- billets for the isothermal forging
