Tungsten Carbide
A metal/ceramic hybrid, combining the properties of metals and ceramics into a single material suitable for the
toughest applications.
- Almost as hard as diamond
- Valued for its excellent abrasion resistance, strength and durability
General Overview
Tungsten Carbide is a metal/ceramic hybrid, combining the properties of metals and ceramics into a material suitable for the toughest applications.
Tungsten carbide is a chemical compound made by reacting tungsten metal with carbon. Pure tungsten metal has excellent corrosion resistance but is soft enough to be cut with a hacksaw. By introducing carbon, you greatly increase the hardness until it’s almost as hard as a diamond.
In practice, most tungsten carbide products are made by taking ultra-fine grains of pure tungsten carbide and cementing them together with a small amount of a second metal – generally cobalt. The result is ‘cemented’ tungsten carbide, a powerhouse material with extreme hardness, immense strength, and excellent corrosion resistance.
