Custom designed Cemented Carbide industrial knives with Steel or Stainless Steel body for various shredding and granulating machinery. In 2019 we manufactured 13.000 OEM knives. Design to customer specifications, life expectancy, customer owned design/patent, price on request.
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.
