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. | GSGrade | ISO Grade | Density (g/cm3) | Hardness (HRA) | T.R.S (MPα) | Grain Size | Performance & Application Recommended | | RX10 | K20 | 14.6-15.0 | 90~90.5 | 2200~2400 | Medium | High hardness, suitable for roughing of iron, solid wood, dry wood
or nonferrous metal, ceramic and other alloys. | | RX20 | K30 | 14.6-15.0 | 90~90.5 | 2600~2800 | Fine | High toughness, easy to be brazed without heat preservation.
Suitable for rosewood, solid wood, pinewood, and other wood with a
lot stammer. | | RX10T | K10 | 14.6-15.0 | 92.5~93 | 1800-2000 | Ultrafine | High hardness, suitable for finishing of iron, nonferrous metal,
