1. Tungsten powder has high purity, uniform particle size and good dispersion. It is an important raw material for the production of tungsten carbide powder
2. Tungsten carbide powder is the main raw material for processing cemented carbide and has more excellent properties.
3. Tungsten powder not only has high hardness, but also has the characteristics of wear resistance, corrosion resistance and high temperature resistance.
4. The melting point of tungsten is 3400 ºC. Boiling point 5555 ºC, insoluble in water, strong acid and alkali resistance.
5. The hardness of tungsten is the hardest among metals. The hardness of sintered tungsten rod is 200 ~ 250 and that of tungsten rod passing through rotary hammer is 350 ~ 400.
