Silicon Carbide Ball Description

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.

Advanced Ceramic Materials (ACM) Corporation produce sintered SiC balls, reaction bonded SiC balls and recrystallized SiC balls. Our recrystallized SiC products have a high purity, while our reaction bonded and sintered silicon carbide balls have a high mechanical strength. Our silicon carbide balls possess good wearability, a low thermal expansion coefficient, extreme corrosion resistance, high hardness and self-lubricating properties.

Silicon Carbide (SiC) Ball
Average rating:

by Terry Grant on Silicon Carbide (SiC) Ball
very strong and durable

Appeared powdery on arrival, but don't be alarmed by this. They are very durable non-powdery. Did a variety of test on strength durability.
- high impact test
- drop test
- velocity impact test
- stress test
These are as strong as steel (or at least close enough)
