Does Tungsten Carbide Contain Cobalt?

Tungsten carbide (WC), particularly tungsten carbide cobalt (WC-Co), is a composite material celebrated for its exceptional hardness, wear resistance, and versatility across numerous industrial applications. Often referred to as cemented carbide, this material typically comprises 70-97% tungsten carbide, with cobalt making up the remaining portion. The specific ratio between tungsten carbide and cobalt can be adjusted to achieve desired material properties. Higher tungsten carbide content generally enhances hardness and wear resistance, while increased cobalt content improves toughness and shock resistance.
