Brown fused corundum is an abrasive composed mainly of aluminium oxide and is almost iron-free. Brown fused corundum produced while fusing calcined bauxite at higher than 2000 °C temperature in an electric arc furnace. Brown fused corundum abrasive is durable and extremely hard material (9 in Mohs scale), angular shape with renewing edges. This abrasive is also ecologically clean and free of not respirable crystalline silica (SiO2). It has relatively high thermal conductivity and low thermal expansion.
