Import Brown Aluminium Oxide — Buy in Bulk from Supplier in China

Brown aluminium oxide from Zhengzhou Integrity Industry Co., Ltd. is a fused bauxite abrasive with a Mohs hardness of 9, supplied in multiple grit sizes for grinding, blasting and polishing tasks. The material is produced through an electric arc furnace process, yielding a tough, angular grain that resists fracturing under heavy workloads. This origin in Henan positions the supplier near key raw material sources, supporting consistent feedstock quality.

The abrasive is composed of aluminium oxide with trace iron and silicon oxides, giving it the brown colour and a density typically around 3.9 g/cm3. Standard grain shapes include angular and rounded, with typical bulk densities ranging from 1.5 to 1.9 g/cm3 depending on grit size. Industry practice often classifies brown aluminium oxide by FEPA or ANSI grit standards, with common sizes from 16 to 220 mesh for coarse to medium applications. The material is chemically stable and recyclable, a feature valued in foundries and metal fabrication.

Primary buyers include steel mills, foundries and surface preparation contractors who use it for cleaning castings, deburring metal parts and preparing surfaces for coating. The product is packed in 25 kg or 50 kg paper sacks, with bulk options available for industrial users. Zhengzhou Integrity Industry Co., Ltd. offers FOB Zhengzhou terms, with lead times and MOQs to be confirmed directly with the supplier. This abrasive is suited to dry or wet blasting systems, with typical service life extending over multiple cycles in well-maintained equipment.
