Tungsten Carbide Balls Applications
The applications of tungsten carbide balls are extremely broad, such as: precise bearings, 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 from Chinatungsten Online 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.
The process of making tungsten carbide balls
Heading a ball
To remove the "ring" around the ball, the slugs are then flashed. This flashing gives the ball a rough finish
After flashing, the rough balls are then heat treated. This high temperature process hardens the ball.
After the ball is heat treated, the ball is then ground to the approximate diameter of the finished tungsten carbide balls.
After the ball is ground to approximate size, the ball is then lapped. This lapping process polishes the ball to the exact size required. This gives the tungsten carbide ball a shinny finish.
After the balls are removed from the lapping process the balls are inspected. This is done mechanically and visually. The balls are measured either through a fine tuned tapered roller or by a digital micrometer. These devices are capable of measuring within millionths of an inch. Once it is determined that the balls are within measured specifications, they are visually inspected through a high powered microscope. Once they are approved by quality control, the balls are then packaged and shipped to the customer.
