COBALT BINDER
NICKEL BASED BINDER
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, flow meters, ball screws and linear bearings. Balls from this material are also used for ballizing, gauging and ball pens.
Conventional Tungsten Carbides (with Cobalt binder) has limited corrosion resistance, which makes them unsuitable for applications in which the wear parts are operating under both severe abrasive and corrosive conditions. As a general rule straight Tungsten Carbide (with Cobalt Binder) is resistant to corrosion down to pH 7. By comparison, tests have shown that our Tungsten Carbide (with Nickel binder) material is resistant to corrosion down to pH 2 or 3.
