High hardness and dimensional stability make tungsten carbide balls the
preferred choice for precision hydraulic valves, high-load bearings, inertial
navigation systems, ball screws, linear bearings in slideways, gauging and
checking instruments, and meters. Tungsten carbide balls are also used for
ballizing, to work-harden and improve fretting fatigue strength.
Tungsten carbide balls are ideal for applications where extreme hardness must be accompanied by high resistance to wear and impact. They are well-suited to elevated temperatures, corrosion, humidity, abrasion, and poor lubrication conditions.
