0-1mm 1-3mm 3-5mm white fused alumina refractory material

$800.00$850.00 / MT

White fused alumina is made in arc furnace with high grade processed alumina as raw materials. It has higher hardness , high toughness, and also characterized by its high purity. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel. also widely used for bonded and coated abrasives, polishing, precision casting and so on.
