Brown Fused Alu. Oxide

Brown Fused Alu. Oxide’s principal component is aluminum oxide with brown color. It is made from high-quality bauxite by fusing in a tilt-pour or fixed electric arc furnace. Brown Fused Alu. Oxide features toughness and impact strength. It can bear high pressure. Its Knoop hardness is 1800-2200kg/mm2. It`s suitable for making bonded and coated abrasive tools, wet or dry blasting,super-precision grinding and polishing, making high-quality refractory materials, grinding carbon steel, alloy, malleable cast iron, hard bronze, and semi-conductor materials.
