Pure Corundum is extremely hard, ranking just below diamond. It ranks 9.0 on Mohs scale of hardness. It is commonly used as an abrasive, such as sandpaper and large machines used in machining plastics, woods and metal.
Abrasive corundum is synthetically manufactured from bauxite.
Corundum is a less commonly used term for an abrasive product known as aluminum oxide. It is also used as a loose grain abrasive in abrasive blasting applications. It's hardness and agressiveness make it an ideal abrasive for imparting a profile on the part substrate.
