Properties of Tungsten Carbide Ball
The main ingredients are tungsten and cobalt alloy (wc-co) with high hardness. HRA90-92.
Good abrasion resistance. The abrasion resistance of tungsten carbide ball is dozens to hundreds of times of that of steel ball.
Good chemical stability and long service life.
Application of Tungsten Carbide Ball
Tungsten carbide balls are used in a wide range of fields, such as: precision bearings, instruments, meters, pens, sprayers, high short-circuit current automatic selection switches, pumps, mechanical parts, sealing valves, brake pumps, punching holes, oil fields, hydrochloric acid laboratory, hardness measuring instrument, fishing gear, decoration field, finishing process, manual switch, drum controller, cam controller, battery car contactor and other electrical appliances, etc., with wear resistance, anti-welding.
