Silicon carbide

Highly stable, very hard and extremely versatile synthetic abrasive.

Silicon carbide, hard yet versatile 

Silicon carbide (SiC) is a highly stable and very hard abrasive with excellent thermal shock resistance. SiC is produced synthetically in electrical resistance furnaces, using the Acheson process invented in 1891. We produce it in Salto, Brazil, under our flagship Alodur® silicon carbide brand in a variety of particle size distributions. 

Harder even than aluminum oxide, silicon carbide is the hardest common abrasive grain, measuring 9.5 on the Mohs scale of hardness, very close to that of diamond. As a blasting media, it has a very fast cutting speed, also benefiting from a high degree of recyclability. Its long-lasting nature means it is well suited for use on harder materials, rougher surfaces and for wet polishing, due to its friability, hardness and sharpness. It is ideal for hard metals, glass, stones, and marble. Its versatility means it can be used for a large amount of abrasive applications.
