Titanium Zirconium Molybdenum Alloy
Titanium Zirconium Molybdenum (TZM) Alloy is a molybdenum-based alloy with added titanium and zirconium for enhanced properties. This high-performance alloy is engineered to deliver superior strength, stability, and creep resistance at elevated temperatures. TZM offers great thermal conductivity and low thermal expansion. As one of the most often used molybdenum-based alloys, it is ideal for demanding applications in aerospace, defense, electronics, and high-temperature industrial environments.
Offering extraordinary strength at the isothermal forging temperature, TZM Alloy is an ideal material for forging dies and related components. It also improves grain structure, significantly boosting mechanical performance under heat and stress. The strength and creep resistance at extremely high forging temperatures is strengthened by the titanium and zirconium carbides in this alloy, enabling the use of elevated materials without the loss of strength when pure molybdenum is utilized in the forging process.
TZM: Titanium, Zirconium, Molybdenum
TZM alloy is comprised of Titanium, Zirconium, and Molybdenum. It contains 0.50% titanium (Ti), 0.08% zirconium (Zr), with the balance molybdenum (Mo). Uniquely, the titanium and zirconium carbides increase strength and creep resistance at elevated temperatures. The use of TZM also enables higher service temperatures without loss of strength in comparison to pure molybdenum.
