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 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 is a high-hardness synthetic abrasive, manufactured from bauxite smelted in an electric arc furnace at ultra-high temperature. It is the most widely used and cost-effective blasting abrasive for industrial surface treatment.
Brown Fused Alumina is a premium blasting abrasive that offers an unbeatable combination of speed, durability, surface quality, and operator safety.
