Grade: TZM
Formula: Mo 99/Ti 0.5/Zr 0.1
Form: Rod
Material: Molybdenum
Commodity: Alloys
TZM Molybdenum Alloy Rod delivers superior mechanical strength, thermal stability, and wear resistance compared to pure molybdenum, due to alloying with titanium and zirconium carbides. In rod form, it offers high load-bearing capacity and excellent creep resistance at temperatures exceeding 1000 °C. Industries such as aerospace, nuclear power, and advanced manufacturing rely on TZM rods for furnace shafts, structural reactor components, and high-temperature tooling. Specific applications include extrusion dies, hot working tools, and high-stress aerospace engine parts. In research, TZM rods are studied for fatigue resistance, radiation damage tolerance, and microstructural optimization under extreme thermal cycling. Their unique blend of elevated-temperature strength, machinability, and corrosion resistance makes TZM molybdenum alloy rods indispensable for critical engineering designs that demand reliable long-term performance.
