Brown Fused Alumina (BFA) is produced by melting high-quality bauxite in an electric arc furnace. It features sharp angular grain shape, high hardness (Mohs 9.0), good mechanical toughness and moderate self-sharpening property.

Brown Fused Aluminum Oxide Powders are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools and lapping and polishing processes.

Brown aluminum oxide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown color, high hardness and great toughness. The abrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze.

Brown fused alumina is made of bauxite, anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000 degrees. suitable for grinding, polishing, blasting, precision casting etc. brown fused alumina is also used for refractory material.

Beacasue of the superior hardness, toughness, safety and cost-effectiveness, brown fused alumina has become the mainstream abrasive for metal surface treatment, especially for steel blasting projects worldwide.

Brown fused alumina is the standard abrasive for conventional flap discs. It balances grinding efficiency, durability and cost, and is the first choice for general metal grinding, weld treatment and surface conditioning across industries.
