What are the specific metal alloys of tungsten carbide？

Tungsten carbide is not a traditional metal alloy; rather, it is a composite material consisting of tungsten (W) and carbon (C) atoms. The primary form of tungsten carbide is represented by the chemical formula WC, where tungsten and carbon are combined in a one-to-one ratio. This compound exhibits exceptional hardness, wear resistance, and strength.

The tungsten carbide matrix can be further enhanced by the addition of a binder phase, often cobalt (Co), to improve toughness and provide cohesion to the material. The resulting composite is commonly known as cemented carbide or hard metal. The binder phase, typically present in the range of 6% to 25% by weight, helps bind the tungsten carbide particles together during the sintering process.

In summary, tungsten carbide alloys are primarily composed of tungsten carbide particles (WC) and a binder phase, commonly cobalt (Co). The specific composition and characteristics of tungsten carbide alloys can vary based on the desired properties for a particular application, including hardness, toughness, and wear resistance. Different grades of tungsten carbide alloys may be developed by adjusting the proportions of tungsten carbide and the binder phase, as well as incorporating additional alloying elements for specific performance requirements.
