1. What are Silicon Carbide Balls?

Silicon Carbide Balls are precision or ceramic spheres manufactured from SiC, an advanced ceramic known for its high hardness, excellent wear resistance, thermal stability, and chemical resistance.

2. What are Silicon Carbide Balls used for?

SiC balls are used in grinding and milling, ceramic bearings, chemical processing, wear-resistant components, high-temperature equipment, pumps, valves, laboratory equipment, and advanced ceramic systems.

3. What sizes are available?

REG Metals can source small precision ceramic balls through larger industrial SiC spheres, with custom diameters and dimensional tolerances available.

4. Why use Silicon Carbide instead of steel or alumina balls?

Silicon carbide provides an excellent combination of high hardness, low density, high-temperature capability, chemical resistance, low thermal expansion, and wear resistance, making it suitable for demanding environments.

5. Can Silicon Carbide Balls be polished?

Yes. Ground, lapped, and polished SiC balls can be sourced with controlled surface roughness and dimensional tolerances for precision applications.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting SiC purity, density, diameter, dimensional tolerance, hardness, surface finish, and other applicable material specifications.
