Import Aluminum Oxide — Buy in Bulk from Supplier in China

Brown aluminum oxide from China Abrasives Import & Export Corporation is electrically fused in an arc furnace from bauxite at high temperature, producing a brown-coloured abrasive with high hardness and toughness. The material is engineered for durability in grinding and cutting applications, with the brown variant specifically suited to steel, malleable cast iron, and hard bronze. White aluminum oxide, also part of the supplier’s range, offers a slightly higher hardness and toughness, making it ideal for fine grinding of high-carbon steel, high-speed steel, and stainless steel.

The brown grade is commonly deployed in abrasive tools, while the white variant is used for precision casting and high-grade refractory applications. Brown aluminum oxide typically features a Mohs hardness of 9, a density around 3.9 g/cm³, and a melting point above 2000°C, properties that underpin its use in demanding environments. The white variant, with its finer grit sizes, is often selected for applications where surface finish and material removal precision are critical.

Industries sourcing this material include metal fabrication, foundries, and refractory manufacturers. Brown aluminum oxide is frequently used in bonded abrasives, coated abrasives, and blasting media, while the white grade finds use in lapping, polishing, and as a filler in specialty ceramics. Buyers typically confirm grit size distribution, bulk density, and chemical purity to match their process requirements.

China Abrasives Import & Export Corporation is based in Zhengzhou, Henan Province, at No.183 Zhongyuan West Road.
