Tungsten carbide is a type of steel

Tungsten carbide is a type of steel. It is comprised of mainly tungsten carbide and cobalt. The cobalt acts as a binder and improves shock resistance. As the percentage of cobalt in the mix rises, so does the shock resistance. These materials generally start as powders. A small amount of wax is then added to the mix. This holds the materials together so they can be molded. The mix is then placed in a de-waxing furnace overnight. It is removed and takes a more chalk like appearance. (S1, p1) As a result of this, a material is obtained which combines high strength, toughness and high hardness.
