Product Description
Features
1. Tungsten powder has high purity, uniform particle size and good dispersion. It is an important raw material for producing tungsten carbide powder
Tungsten carbide powder is the main raw material for processing cemented carbide, which has more excellent properties.
2. Tungsten powder not only has high hardness, but also has the characteristics of wear resistance, corrosion resistance and high temperature resistance.
3. The melting point of tungsten is 3400 º C. Boiling point 5555 º C, insoluble in water, acid and alkali resistant.
Tungsten is the hardest metal. The hardness of sintered tungsten rod is 200~250, and the hardness of tungsten rod passing through rotary hammer is 350~400.
