Tungsten carbide Wikipedia

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, WPCpiercing shells and jewellery.

Tungsten Wikipedia

Tungsten is mainly used in the production of hard materials based on tungsten carbide WC, one of the hardest carbides. WC is an efficient electrical conductor , but W 2 C is less so. WC is used to make wearresistant abrasives , and carbide cutting tools such as knives, drills, circular saws , dies , milling and turning tools used by the
