Cemented carbide composition and performance

Cemented carbide is a tungsten carbide hardness and high melting point (known as the hard phase) and a metal (called the binder phase) made ​​by powder metallurgy process.Tungsten carbide tool commonly used carbide such as WC, TiC, TaC, NbC. The adhesive generally used is Co; titanium carbide-based adhesive is Mo, and Ni. Tungsten carbide physical and mechanical properties depend on the alloy composition and thickness of the powder particles as well as alloy sintering process. More hard phase of high hardness and high melting point Contains, the higher the hardness and high-temperature hardness of the alloy. Containing the more binder, the higher strength is.
