Brown Alumina Powder For Grinding Stone
Brown fused alumina powder from Zhengzhou Haixu Abrasives is manufactured by smelting bauxite and anthracite coal in electric-arc furnaces at temperatures exceeding 2000°C. The result is a brown aluminium oxide with a minimum Al2O3 content of 92%, SiO2 capped at 2%, Fe2O3 at 2%, and TiO2 at 4%, delivering a Mohs hardness of 9.0 and a melting point of 2250°C. Its bulk density ranges from 1.53 to 1.99 g/cm³, with a specific gravity of 3.6 to 3.9 g/cm³, making it suitable for high-stress grinding and finishing applications.
This brown fused alumina maintains high purity and crystalline fluidity, with low linear expansion coefficients and resistance to corrosion and thermal shock. It is available in grain sizes from 0-1mm to 5-8mm, fine powders from 0-100 mesh to 0-320 mesh, and grit sizes from 8# to 220#, with micro powders in FEPA F230 to F800 and JIS #240 to #2000. These variants cater to bonded and coated abrasives, surface preparation, refractory materials, and precision applications like grinding optical glass, monocrystalline silicon, and jadeware.
Industrial buyers source this abrasive for grinding high-tensile metals such as steel, malleable iron, and bronze, as well as for abrasion-proof surfacing on expressways, airstrips, and docks. It is also used in thermal spraying, lapping, and micro-blasting, with applications extending to super refractories, ceramics, and tiles. Bulk shipments are typical for global trade, with packaging and lead times confirmed directly with the supplier.

Sourcing Brown Alumina Powder For Grinding Stone from Zhengzhou Haixu Abrasives Co., Ltd. - China Import Guide
Before ordering, verify the Al2O3 content and impurity limits, as these directly impact the abrasive’s performance in your specific application. Request a certificate of analysis to confirm the chemical composition, particularly for high-precision uses like optical grinding or refractory manufacturing.
Confirm the available grain and grit sizes, as these determine the finish and material removal rate. For bulk orders, agree on Incoterms such as FOB or CIF, and clarify payment terms, as these can vary by shipment size and destination. Port of loading in China should also be specified to estimate logistics costs accurately.
Inspect the bulk density and specific gravity upon receipt, as variations can affect mixing ratios in bonded abrasives. Request a material test report to ensure compliance with your quality standards. For refractory applications, confirm the maximum service temperature meets your operational requirements, and arrange third-party inspection if needed.
