Silicon Carbide is next to diamond in hardness, characterized by its sharp sliver like grains making it superior for its ability to penetrate with light cutting pressures. It is primarily used for grinding nonferrous materials such as brass, copper, bronze and aluminum. Other applications of Silicon Carbide include grinding of glass, wood, rubber and plastics. It is used also to finish polyurethanes, primers, lacquers and sealers.
