Corundum technical data sheet
Corundum is a natural or synthetic abrasive based on aluminum oxide (Al₂O₃), characterized by a very high hardness, second only to diamond and some silicon oxides. Its compact and resistant crystalline structure makes it extremely effective for removing oxidation, paints, residues, and surface layers from hard materials without losing shape or performance during use.
