Standard Fractional Tungsten Carbide Balls
The most common tungsten carbide ball material is generally referred to as C1/C2. Most standard fractional inch TC balls are available off the shelf, many other sizes and grades are also available from stock or special order. Tungsten carbide balls are used where extreme hardness and wear resistance is required in such applications as ballizing, bearings, ball screws, valves and flowmeters. Tungsten carbide balls may also be brazed onto a stem or shank to be used for valves, gauges, or other applications.
Standard Decimal Tungsten Carbide Balls
Industrial Tectonics Inc manufactures a standard line of ABMA Grade 24 tungsten carbide balls between 0.0050” and 0.6250” which are referred to as P59’s. P59 TC balls are available in increments of 0.0001” from stock. P59 tungsten carbide balls are always manufactured to the plus side (+0.0001”/-0.0000) of the ABMA tolerance for grade 24 balls. Many other TC ball sizes both larger and smaller are also available from stock or may be manufactured to order. Tungsten carbide balls are used where extreme hardness and wear resistance is required in such applications as ballizing, bearings, ball screws, valves and flowmeters. Tungsten carbide balls may also be brazed onto a stem or shank to be used for valves, gauges, our other applications.
Ballizing with Tungsten Carbide Balls
Low-cost, high-speed hole sizing and finishing
Ballizing or ball burnishing is a fast low-cost process to sizing and finishing tubing and holes in metal. Pressing a slightly oversized tungsten carbide ball through the unfinished hole brings the hole up to desired size in seconds. The resulting surface finish is excellent and both size and finish results are very consistent. Industrial Tectonics can provide application assistance.
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. Hartford Technologies’ standard material is made of 94% tungsten carbide and 6% cobalt binder, the industry code is C2 tungsten carbide.

Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves, flowmeters. TC balls are also used for coining and pivots, detents and tips for gages and tracers. Decimal-inch size tungsten carbide balls are widely used for ballizing or hole sizing. TC balls are also used for gauging and checking.
