Tungsten carbide powder is dark gray, metallic luster, hardness close to Diamond, to electricity and heat conductors. 2,870 melting point℃, relative density of 15.63, mainly used in the production of cemented carbide. Tungsten carbide is insoluble in water, hydrochloric acid and sulphuric acid, soluble in nitric-hydrofluoric acid in mixed acids. Tungsten carbide is fragile,if mixed with small amounts of metals such as titanium, cobalt, and will be able to reduce brittleness.As a steel cutting tool tungsten carbide,often adding titanium carbide,tantalum carbide, or their mixtures, to improve its explosive capability. Chemical properties of tungsten carbide. High temperature oxidation resistance of tungsten carbide is not enough when the temperature reaches 500℃-800℃, easily into W2C and carbon dioxide in the air. This can be achieved by using heat-resistant metal oxide coating or bonding phase, to pre-protected tungsten carbide particles.Can also be combined with TaC, TIC solution form carbides,improving the thermal oxidation resistance of tungsten carbide. Tungsten carbide in Ar atmosphere heated to 2850 taken remained stable at high temperature in nitrogen are not affected.
 
Tungsten carbide powder and application

1. the massive structure for high speed cutting tools, kiln materials, Jet engine components, ceramic materials, electric resistance heating elements made of metal.
2.tungsten carbide powder is widely used for the manufacture of cutting tools, wear parts, metals such as copper, cobalt, bismuth melting Crucible, wear-resistant semiconductor films.
3. for superhard tool materials, wear-resistant materials. It can form a solid solution and many carbides. Tungsten carbide cutting tools have been widely used.
 

oxidation resistance of tungsten carbide powder quality control

  • all raw material are tested in terms of density, hardness and T.R.S before use.
  • There are strict inspection on process and final products.
  • every batch of product can be traced.
