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.
Corundum has some electrical uses, and non gem quality material, such as emery, is extensively used as an abrasive because of its high hardness.
The most common ore of aluminium is bauxite.
Corundum.
Bauxite is the by far the most common.
Bauxite . Chemically it is Aluminium oxide (Al2O3)
Ruby is the common name for the reddish variety of the mineral corundum. Blue corundum is called sapphire.
Aluminium Hydroxide
