Product Detail

APPLICATION

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.
