Tungsten carbide(also named as cemented carbide) a kind of material made from combination of tungsten and carbon(with formula WC) with cobalt binder,it could keep stable property under high temperature 800ºC with high compressive strength,high hardness and strong resistance to wear,which make tungsten carbide cutting tools a perfect choice for many industrial needs.
Tungsten carbide rod is the preferred material for metal cutting tool manufacturing, widely used in the industries which has high requirements for wear-resistance, corrosion-resistance and high-temperature resistance. It has a lot of outstanding performance.
