Tungsten carbide plates are mainly made from wolfram carbide and cobalt powder by powder metallurgy methods. The main production process of tungsten carbide block is powder milling, ball milling, pressing and sintering. For different uses, the content of WC and Co in tungsten carbide sheet is not the same.
Tungsten carbide plate is mainly used to make high-speed die and multi-station progressive die for punching copper, aluminum, stainless steel, cold-rolled sheet, EI sheet, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punches, etc. It is also an excellent material for making high-temperature resistance parts, wear-resistant parts, anti-shielding parts, anti-radiation, and corrosion-resistant parts.
