TUNGSTEN CARBIDE (WC) YN6 Ni BINDER ALLOY BALLS


Tungsten Carbide with Ni binder (6%) balls, they show slightly worse mechanical characteristics but better corrosion reistance properties with respect to the Cobalt binder tungsten carbides. Virgin powder is always used.

 

Applications

Special bearings, pumps and valves, dispensers, nozzles/pumps for sprayers, ballpoint pens. They are used in mining and petrol industry.
