Cemented Tungsten Carbide
Cemented tungsten carbide is a sintered material mainly consisting of tungsten carbide and a binding agent. The main binder is usually cobalt. If the focus is on creating corrosion resistance, nickel or nickel/chromium is used.
It’s the mix that matters: The binder content and the grain size of the carbides determine the specific tungsten carbide features. A high content advances toughness. A lower binder content increases wear-resistance. The choice of grain size in turn affects hardness. The finer the grain, the harder the material. The coarser the grain, the higher the fracture toughness.
