Tungsten Carbide Balls
Profile
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 standard for Rockwell testing, and for Brinell
Testing of materials in the range of 444-627 HB.
Characteristics
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.
