Cast tungsten carbide powder
Product Description
WC Appearance:
Dark gray powder polygonal smooth particles
Characteristics:
1. Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide. Its hardness is similar to that of diamond.
2. Tungsten carbide powder not only has high hardness, but also has the characteristics of wear resistance, corrosion resistance and high temperature resistance.
3. Melting point of tungsten is 2860 ºC± 50 ºC, boiling point is 6000 ºC, relative density is 15.63 (18 ºC), insoluble in water, strong acid resistance, high hardness and elastic modulus.
4. Pure tungsten carbide is fragile. If a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide, which is used as a steel cutting tool, is often added with titanium carbide, tantalum carbide or their mixture to improve its explosion resistance.
Application:
Wildy used in mining petroleum, metalluggical industry constructionmachunery agricultural machinery and steel industries,for explample PDC bits and other penetration manufacturing products in the oil drilling industry. it can be used for cutting type scraper type bit roller bit and the mechanical industry the com bination of machine tools machining centers used in the surface reinforcement
