Brown Fused Aluminum Oxide(BFA) HS Code 28181010, CAS No. 1344-28-1, is characterized by good toughness, high mechanical resistance and hardness (9 in Mohs scale). The micro hardness of the material reaches about 1900kG/mm2. Specific gravity (density) equals 3,90+/-0,05 g/cm3. Bulk density depending on size equals 1,68-1,95 g/cm3. It has relatively high thermal conductivity and low thermal expansion. As regards electricity it is an insulator.
We manufacture brown fused aluminum oxide in tilting furnace or fixed furnace, and tilting furnace brown fused aluminum oxide has higher Al2O3 content, lower impurities and high-performance. Brown fused aluminum oxide can be crushed and milled by barmac mill, ball mill or roller mill, and brown fused aluminum oxide milled by Barmac equipment is granted more round shape and higher bulk density. Refractory products made of it have higher density and strength, and also less opportunity to have cracks.
