TUNGSTEN CARBIDE (WC) YN9 Ni BINDER ALLOY BALLS


Tungsten Carbide with Ni binder balls (9%), they provide a better corrosion resistance and slightly worse mechanical properties than YN6 type balls.

Virgin powders always used.

 

Applications

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