High Precision Gray Tungsten Carbide Flat Stock Polished / Sintering Surface
It is widely used as a high-speed cutting tool, kiln structural material, jet engine parts, cermet materials, and resistance heating elements.
It is used to manufacture cutting tools, wear parts, smelting crucibles of metals such as copper, cobalt and bismuth, and wear-resistant semiconductor films. Used as super hard tool material and wear resistant material. It forms a solid solution with many carbides. WC-TiC-Co carbide tools have been widely used. It can also be used as a modified additive for NbC-C and TaC-C ternary system carbides, which can reduce the sintering temperature while maintaining excellent performance and can be used as aerospace materials.
The tungsten carbide (WC) powder was synthesized by using tungstic anhydride (WO3) and graphite in a reducing atmosphere at a high temperature of 1400 to 1600 °C. The dense ceramic product can be obtained by hot press sintering or hot isostatic pressing.
