TZM is a particle-strengthened molybdenum based alloy containing titanium, zirconium, and carbon. TZM is widely used in the aerospace, aviation, and other industries. It could be used as nozzle material, valve body, gas piping materials, tubes in the gate material, die casting molds, extrusion dies and high-temperature furnace heating element and heat shield etc.
Mo-La Alloy can work at higher temperatures.
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.
TZM alloy is commonly used as structural material in thermally loaded applications or as plate material in rotary X-ray tubes.
Compared to pure molybdenum, TZM exhibits a higher strength and creep resistance. Especially at elevated temperatures, the primary strengthening mechanism was attributed to carbide particles.
Several types and grades of molybdenum alloys are available commercially. TZM wrought bar was selected as the most suitable material on the basis of its superior high-temperature tensile strength and a high recrystallization temperature (between 1400 and 1600 C). A high recrystallization temperature is particularly important as this eliminates the possibility of recrystallization during brazing welding causing a loss in ductility and strength.
By means of solid-solution and carbide-strengthening, TZM features improved high-temperature strength up to 1400 °C and a higher recrystallization temperature, compared to pure Molybdenum.
Typical Applications of TZM: Components for heat treatment equipment, supports, fixtures, carriers, hot runner nozzles, casting molds, forging dies and others.
