Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide is the hardest of the conventional abrasives but has lower impact resistance than aluminium oxide and shows a higher wear rate when used for grinding steels. Silicon carbide wears more rapidly when used to grind metals that have an affinity for carbon such as iron and nickel. It is therefore used primarily for non-ferrous materials.
