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.

Brown Fused Alumina (BFA) is one of the most popular and cost-effective blasting abrasives for glass processing. Here’s a comprehensive guide to its use, advantages, and critical considerations.

Brown fused alumina (BFA) is a synthetic abrasive smelted from bauxite in an electric arc furnace at high temperature. It is the most widely used raw material for whetstones, sharpening stones and oil stones.

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 suitable for carbon steel, stainless steel, iron, aluminum alloy, copper, glass, ceramics, stone and most hard industrial materials. It is a universal and high-quality blasting abrasive replacing low-efficiency and high-pollution abrasives like quartz sand.

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.
