Hardness

Tungsten carbide measures a nine on Moh's hardness scale, meaning it is about as hard as corundum, but not as hard as diamond. In order to polish or finish an item made of tungsten carbide, a diamond must be used because any other metal or mineral would crack and break. Only a diamond is hard enough to be able to scratch tungsten carbide. Its density also surpasses the density of titanium.

 

Composition and Properties

Tungsten carbide is created when tungsten and carbon are combined in equal amounts. In order to create tungsten carbide, the process has to be carried out at temperatures between 1,400 and 2,000 degrees centigrade. The resulting product, tungsten carbide, has an extremely high melting point of about 5,200 degrees Fahrenheit and a low electrical resistance, meaning it readily conducts electricity.
