Hubei Fotma Machinery Co.Ltd established in 2004 as a combined group engaged into manufacturing and exporting of Non-Ferrous Metals, Agricultural Machinery and Instruction Machinery etc. In 2005, our factory established in Zigong, Sichuan P.R., which is a professional manufacturer of cemented carbide products and finished machining for the tungsten & molybdenum products. We mainly focus on cemented carbide products, and the tungsten & molybdenum and other products as the salutary complementarities......
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.
