TZM alloy has the characteristics of high melting point, high strength, high elastic modulus, small linear expansion coefficient, low vapor pressure, good electrical and thermal conductivity, strong corrosion resistance and good high-temperature mechanical properties, so it is widely used in many fields.
People add trace amounts of titanium and zirconium and other elements to molybdenum to form trace element alloying alloys (such as Mo-0.5Ti, Z-6, etc.) to remove the grain boundary embrittlement phase through solid solution strengthening of trace elements. Its reactants (TiC, ZrC) act as dispersed phases to strengthen the alloy and improve its performance.
Molybdenum alloy contains more than 99.2% to a maximum of 99.5% molybdenum, 0.50% titanium and 0.08% zirconium and carbides. TZM alloy (molybdenum zirconium titanium alloy) is twice as strong as pure molybdenum at temperatures above 1300°C. The recrystallization temperature of TZM alloy is about 250°C, higher than that of molybdenum, which provides better weldability.
TZM alloy (Molybdenum Zirconium Titanium Alloy) can be used to make components of static pressing, sintering and heat treatment furnaces, annealing and sintering process boats (temperature up to 1400'C), medical diagnostic rotating anodes and forming tools, such as hot runner nozzles for plastic injection molding, light alloy casting molds and isothermal forging of steel billets made of molybdenum alloys (titanium, zirconium, molybdenum).
TZM alloy (Molybdenum Zirconium Titanium Alloy) can also be used in mold inserts for casting aluminum, magnesium, zinc, iron rocket nozzles, hot stamping parts.
