Brown Fused Aluminum Oxide

Brown Fused Aluminum Oxide is an abrasive composed mainly of aluminium oxide and is almost iron-free. Brown fused aluminum oxide while fusing calcined bauxite at higher than 2000°C temperature in an electric arc furnace. Brown fused aluminum oxide 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.
