Import Brown Fused Alumina — Buy in Bulk from Supplier in China

Brown fused alumina, also called brown aluminium oxide, is an industrial abrasive produced by fusing and crystallising bauxite at very high temperatures. Zhengzhou Integrity Industry Co., Ltd. supplies this material from its facilities in Zhengzhou, Henan, China. The product is characterised by high hardness, excellent thermal stability, a consistent particle‑size distribution and compatibility with a range of bonding agents. These attributes are listed in the supplier’s description and make the material suitable for demanding grinding applications.

Fused alumina is typically graded by hardness on the Mohs scale, with brown grades usually falling between 9 and 10. Standard purity levels exceed 99.5 % Al₂O₃, and bulk density is commonly around 3.6 g cm⁻³. Particle sizes are often supplied in the 20‑150 µm range, which provides a balance between cutting efficiency and surface finish. Such specifications align with industry norms for abrasive wheels used in metalworking, automotive component finishing and construction tooling.

The material is used to manufacture grinding wheels, sandpaper and other abrasive products, and is purchased by manufacturers in metalworking, automotive and construction sectors.
