Molybdenum, like tungsten, is a refractory rare metal with a melting point of 2620°C, strong interatomic bonding, small expansion coefficient, high electrical conductivity and good thermal conductivity. The influence of molybdenum on the properties of stainless steel is as follows.
TZM alloy is currently the most widely used molybdenum alloy with the best performance. TZM alloy has good high temperature strength, creep resistance and high recrystallization temperature, so it is often made into nozzles, perforated heads, molds, heat shields and grids in high-power ceramic tubes.
Tungsten alloy is an alloy composed of tungsten and other elements. Tungsten alloy wafers are made of tungsten molybdenum alloy or tungsten thorium alloy or rare earth tungsten alloy or tungsten rhenium alloy. They are often used as power semiconductor devices and electric vacuum devices.
