Aluminum oxide and silicon carbide are both ceramic substances utilized as abrasives, with silicon carbide having harder, sharper grains but being less durable than its aluminum oxide counterpart. While both can be used on nonmetallic surfaces like wood or plastics, silicon carbide cannot withstand higher tensile strength metals such as steel. Brown aluminum oxide is an exceptionally hard and long-wearing abrasive, capable of withstanding several blast cycles on softer materials such as rust and wood. White and pink varieties wear down more quickly but produce smoother finishes. Hardness Aluminum oxide (also referred to as brown fused alumina or AL2O3) is one of the most frequently used synthetic abrasives, often called …
