Cemented carbide ball is a high temperature sintered alloy material composed of refractory metal WC and cementing metal Co or Ni. Its alloy has high hardness and good wear resistance. It is widely used in ball rolling body in bearing industry, rotary ball for fluid sealing, pump valve spool, one-way valve spool and valve seat of petroleum extracting machine, and many other military and civilian high tech fields.
Uses of Cemented Carbide Balls: Precision bearings, instruments, meters, pen making, sprayers, pumps, mechanical parts, sealing valves, brake pumps, punching and extruding holes, oil fields, hydrochloric acid laboratories, hardness measuring instruments, fishing gear, counterweights, decorative, finishing and other high end industries!

Main Features
High hardness: The hardness of cemented carbide balls can reach 90-93 HRA, second only to diamond.
Wear resistance: Excellent anti-wear performance, suitable for high load and high wear conditions.
High density: The density is usually 14.5-15.0 g/cm³, heavier than steel balls.
Corrosion resistance: Excellent performance in corrosive environments such as acid and alkali.
High precision: Can reach G5-G100 precision grade with extremely smooth surface.
High temperature resistance: Good high temperature stability, can work in high temperature environment.
Field of Application
Rolling bearings: Carbide balls are used in high-precision bearings, adapted to high-load, high-speed running occasions.
Valves and seals: Used in high-pressure valves and seals in oil and gas, chemical industry, wear-resistant and corrosion-resistant.
Nozzles: Used in sandblasting, spraying equipment nozzles, with a long life and high wear resistance.
Measuring tools: Used as reference balls for high-precision measuring equipment to ensure the accuracy of measurement results.
Other high load applications: such as aerospace, mining machinery, medical equipment, military and other fields.
Tungsten carbide ball is usually used for high precision bearings, valves, nozzles and other parts in the industrial field. Its international standards mainly involve hardness, dimensional tolerances, surface roughness, compressive strength and other performance indicators.
