WC-12Co Crushed cemented carbide grits

WC-12Co 15-45um Tungsten Carbide Powder with inrregular Size by sintered and crushed power type Tungsten Carbides commonly used for machine parts Tungsten Carbide Coating.Max operating temperature can achieve to 500℃. The Tungsten Carbide Powder material is generally best using for High Velocity Oxygen Fuel (HVOF Tungsten Carbide Coating) or Atmospheric Plasma Spray(APS) Tungsten Carbide Coating. This material offers gas corrosion resistance and impact resistance coating; Apply to high toughness and anti-fatigue coating. Hard and density coating has excellent wear resistance.

Due to tungsten carbide being a hard and brittle ceramic material, when used as a tungsten carbide coating, cobalt, chromium, and nickel elements are mixed together for use. This metal ceramic composite coating combines the ductility of metal materials with the high hardness of ceramic tungsten carbide, thereby achieving excellent performance. By controlling the size of tungsten carbide particles, we can also control the strength, wear resistance, and hardness of sprayed tungsten carbide, which can provide precise performance control when manufacturing tungsten carbide coatings.
