The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. WC/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ceramic.
Oct 15, 2009· In reference to the composition of the cemented tungsten carbide useful for the hard inserts at the axial forward end of the cutting bit, the cemented tungsten carbides may be any one of a number grades of cemented tungsten carbide that are suitable for impingement of earth strata.
Tungsten carbide (chemical formula: WC) is a 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 through a process called sintering for use in industrial machinery, cutting tools, abrasives, armorpiercing rounds, other tools and instruments ...
