Introduction
Tungsten Carbide Balls Applications

Tungsten carbide balls are also called cemented carbide balls, bearing balls or just simply carbide balls.

The applications of tungsten carbide balls are extremely broad, such as: precise bearing balls, instruments, meters, pen, spraying machines, pumps, machinery parts, valve seals, brake pump, extruding hole, oil, hydrochloric acid lab, hardness measuring instrument, fishing gear, with heavy, ornamented, finished, and some other high-end industry!

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 sideways, gauging and checking instruments, and meters. Tungsten carbide balls are also used for balloting, 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.

Tungsten Carbide Balls 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.

Tungsten Carbide Balls Mechanical Properties

Tungsten carbide balls from Zhuzhou Tongda are tested using a gage that is accurate to ±0.0001 (grades 10, 15 and 25) to insure conformance with standards, as well as individual customer quality requirements. Tungsten carbide balls can be polished into extremely high precision, so it also has a wide use as bearing balls.
