Tungsten carbide (WC) is an inorganic chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, other tools and instruments, and jewelry.
Tungsten carbide powder is the intermediate in the line from W powder to cemented carbides. It can be produced from different raw materials and by different processes. By far the biggest percentage is manufactured by the conventional method - carburization of tungsten powder - and covers the widest range of powder qualities in regard to average particle size (0.15–12µm). All other methods in use yield very fine or very coarse powder grades.
Fine tungsten carbide powder, containing ultrafine tungsten carbide powder and and nano tungsten carbide powder, prepared by special process methods, high purity, uniform particle size, good dispersion, and it’s an important raw material in the production of carbide.
Nanometer tungsten carbide powder, has high purity, particle size uniform dispersion of good, is an important raw material of producing cemented carbide, nano tungsten carbide powder can make hard alloy has many more excellent properties.
Cast tungsten carbidepowder's particle size should be in line with powder weight percentage for upper size should be no more than 5%,; for lower size no more than 7%, and the particle size for cast tungsten carbide can be produced according to customers' requirements.
Ready to press tungsten powder has an average particle size of 0.8 μm or less and is free of a coarse powder having a particle size of more than 1 μm.
