Tungsten carbide is a compound consisting of tungsten and carbon atoms in equal parts. It is a dense substance similar to metals and a significant member of the inorganic carbon compound class. It is widely used for imparting hardness for casting iron, penetrating the cores of armor-piercing ammunition, and cutting edges of drills and saw blades. Owing to its properties of being twice as stiff as steel and extremely hard, tungsten carbide is used in various application end-use segments.
