Tungsten Carbide Cobalt Binder
General Information
Tungsten Carbide materials have a unique combination of properties, high compressive strength, hardness and resistance to wear, as well as an ability to withstand shock and impact. Typical applications are valves, flowmeters, ball screws and linear bearings. Balls from this material are also used for ballizing, gauging and ball pens.
