Tungsten Carbide Slitting Knife
Enermof is a professional supplier of tungsten carbide cutting and slitting tools. The manufacturer produces tungsten carbide cutting and slitting blades made by the powder metallurgy method, widely used for cutting non-ferrous metals, cardboard/paper, chemical fibers, graphite, and plastics. Tungsten carbide — composed of WC (hard phase) and cobalt (binder phase) — offers high hardness, wear resistance, and corrosion resistance, making it the ideal material for any cutting device. Different material grades are available for different applications, determined by WC grain size and the percentage of hard and binder phases.
