Tungsten carbide (WC) is a chemical compound comprising tungsten and carbon atoms. It exists most commonly as a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, jewelry and more[1][7]. Tungsten carbide is approximately twice as stiff as steel, and is much denser than steel or titanium[5]. It is comparable to corundum in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder[1].
