Tungsten Carbide Properties
Aug 30, 2018

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, mining and drilling tools, kinds of cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

 

Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530700 GPa and is double the density of steelnearly midway between that of lead and gold. It is comparable with corundum in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels, and compounds.
