Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ...
A very important product of this type is tungsten carbide. [1] Tungsten carbide is used to cut and form other metals and is made from tungsten carbide particles bonded with cobalt. [2] Tungsten carbide is the largest and most important use of tungsten, [3] consuming about 50% of the world supply. [4]
Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [3] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [2]
