Black Corundum is produced in an electric arc furnace by melting bauxite to form an Al2O3 spinel with iron ore phase, resulting in colored crystals. It has lower Al2O3 content and contains approximately 10% Fe2O3, giving it moderate hardness and great toughness, self-sharpening properties, good bonding, and high durability. It generates less heat during grinding, resists high temperatures, and does not easily scratch workpiece surfaces, resulting in high surface roughness. It is used in free grinding of metal parts, aluminum products, bicycles, motorcycles, sewing machines, watches, lighting, plastic and hardware tools, resin cutting blades, angle grinding, coated abrasives, stainless steel polishing, and non-slip surfaces for roads and coal pits.
