  • Product Detail


    Brown Fused Aluminum Oxide(Brown Fused Alumina) is a tough, long-lasting material. It is made from bauxite, carbon materials, iron filings as raw material through melting in the electric furnace. It is brown in color as it has a slightly higher level of impurities than white aluminum oxide. Brown Fused Aluminum Oxide is a high strength, wear-resistant material possessing a strong ability to resist vigorous chemical attacks (such as acid and alkali) at extreme temperatures.  Typical applications for the Brown Fused Aluminum Oxide include blasting and grinding.

    Brown Corundum Powder


    1. Large crystal, high strength, good toughness, dense texture, high bulk density.

    2. Stable performance between batches.

    3. The higher grinding efficiency and polishing brightness, the grinding efficiency is much higher than the soft abrasives such as silica.

    4. Good particle appearance, high surface finish of the polished object.
