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, armor-piercing shells and jewellery.Tungsten
carbide have cobalt and nickel binder type.
Tungsten carbide is approximately twice as stiff as steel, with a
Young's modulus of approximately 530–700 GPa (77,000 to 102,000
ksi), and is double the density of steel—nearly midway between that
of lead and gold.
Tungsten carbide has very high strength for a material so hard and
rigid. Compressive strength is higher than virtually all melted and
cast or forged metals and alloys.
