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.
Tungsten is a rare metal with a shape similar to steel. Because of its high melting point, high hardness, excellent corrosion resistance, and good electrical and thermal conductivity, it has become one of the most important functional materials in modern industry, national defense etc.
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.
Rolled tungsten alloy has the characteristics of high hardness and high strength, which brings a lot of inconvenience to later processing.
