Tungsten carbide granule（WC）产品概况

As a hard wear-resistant coating, WC is widely used in military and civil industrial fields such as national defense and military industry, aerospace, metallurgy, petrochemical, electric power, transportation, water conservancy, marine development, etc., and has become a key technology to solve the wear and corrosion resistance and protection of important parts. In addition to the traditional application fields, WC film can also be applied to micro products (such as micro drill bits for integrated circuits) and small and thin parts, and has broad application prospects in the field of microelectronics (such as diffusion barrier layer of microelectronic devices, conductive film, etc.).

Tungsten carbide (WC) is a typical hard alloy material. WC has very excellent physical and chemical properties, such as high hardness, high wear resistance, good thermal and chemical stability, good oxidation resistance, low coefficient of thermal expansion, high modulus of elasticity, and a certain degree of plasticity. In addition, the performance of WC wetted by most bonding phases is better than other carbides, and its toughness is better than other carbides. In addition, WC also has high thermal conductivity and high conductivity, which is conducive to cutting applications.
