Product Overview

Tungsten Carbide Balls are ultra-hard, high-density precision balls engineered for severe wear, high compressive loads, and demanding service environments where standard steel balls can fail. Tungsten Carbide is made from a combination of tungsten and carbon. Cobalt and nickel may be added as a binder to enhance the balls’ performance. These balls are selected when applications require exceptional resistance to deformation, strong impact performance, and stable operation across extreme temperature swings.

Engineered and tested across thousands of installations based on decades of manufacturing expertise, tungsten carbide balls are widely specified for critical contact points in bearings, valves, flow meters, ball screws, and pens. Their combination of high hardness and wear resistance supports long service life in abrasive conditions. Their high resistance to shocks and impacts and ability to quickly handle extremely low and high temperatures make tungsten carbide ball products a popular option for situations where traditional steel has failed.
