Description of TZM Molybdenum Alloy
Molybdenum (Mo) is gray-metallic and has the third highest melting point of any element next to tungsten and tantalum. It is found in various oxidation states in minerals but does not occur naturally as a free metal. Molybdenum is well-known for its strength and stability in high-heat applications. It is often alloyed with other compounds to improve corrosion resistance and strength at high temperatures. Consequently, molybdenum is frequently used for making steel alloys, high strength alloys, and superalloys. Molybdenum compounds usually have a low solubility in water. Industrially, they are used in high-pressure and high-temperature applications such as pigments and catalysts.
Titanium-Zirconium-Molybdenum alloy (TZM alloy) contains 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon. TZM molybdenum is manufactured by either P/M or Arc Cast technologies. TZM alloy has higher creep resistance and strength than pure molybdenum. SAM produces a wide range of molybdenum and molybdenum alloy mill products including forging billets, bar, rod, sheet, plate, and foil.

Modules of Elasticity
We provide TZM sheet and TZM rod with the same size as pure moly, with the exception of thin foil. TZM is also available in forms of wire, plate, tube, and machined parts. We’re capable of customizing TZM alloy to fit your specific requirements.
Applications of TZM Molybdenum Alloy
TZM alloy is widely used in high-temperature applications (e.g. high-temperature furnace construction and metal working) and in tooling for hot die forging.
Packaging of TZM Molybdenum Alloy
Our TZM alloys are wrapped in foam and packaged in plywood cases to ensure safe storage and transportation.
