Tungsten Carbide Grinding Balls description

Bullo Carbide's tungsten carbide grinding balls are made from 100% virgin tungsten carbide material.

Tunsten carbide balls also called tungsten carbide sphere,it has the features of high hardness, high precision, high anti-rust capability, high wear-resistant and abrasive and so on, which have much longer usage life than steel balls.

Due to its unique features,tunsten carbide balls are widely used in many fields: like steel bearings, instruments, hardware, ball valves, smash, sealing, Machinery, Medical Equipment, Aviation, Perfume Bottles, Sprayers, Valves, Nail Polish, and so on.

Our tungsten carbide balls also usually matched with our tungsten carbide  grinding jars for planterary ball mill.
