Import Artificial Corundum White Grain — Buy in wholesale FOB from Supplier in China

Artificial Corundum White Grain from Zhengzhou Haixu Abrasives is electrically fused in an arc furnace using high-grade processed alumina as the raw material. The product achieves a minimum Al2O3 content of 99.5%, with trace impurities limited to Fe2O3 at 0.08%, Na2O at 0.3%, SiO2 at 0.01%, CaO at 0.03%, and K2O at 0.03%. It exhibits a Mohs hardness of 9, a bulk density of 1.75-1.95 g/cm3, and a specific gravity of 3.95 g/cm3, with a melting point of 2250°C and a maximum operating temperature of 1900°C.

The material’s high purity and self-sharpening properties make it ideal for applications where color integrity of the workpiece is critical, such as in precision grinding of high-carbon steel. Its low iron oxide content (0.08% Fe2O3) ensures no iron residue during blasting operations, which is essential for industries prohibiting iron powder contamination. The fine powder grades are particularly suited for wet sandblasting, polishing, and dermabrasion, while its thermal stability and resistance to acids and alkalis extend its usability in refractory materials and ceramic production.

This abrasive is widely used in bonded and coated abrasives, grinding wheels, sandpaper, and as a raw material for polishing wax and fluid. It also serves as a furnace burden in refractory applications, including castables, ramming compounds, and refractory bricks. Buyers in steel fabrication, automotive braking systems, and wear-resistant flooring industries source this grain for its efficiency in cutting and heat emission reduction, with typical trade terms including bulk packaging and confirmation of MOQ and lead times directly from the supplier.

Zhengzhou Haixu Abrasives Co., Ltd. is based in Zhengzhou, Henan Province, China, with its office located at Room 1903, Yaxing Times Plaza, Erqi District. The company operates as an importer-tier supplier in the abrasives market, specializing in electrically fused alumina products. Its profile indicates a focus on industrial-grade abrasives, with no additional verification signals or response metrics currently available.

The supplier’s product line centers on white corundum and other fused alumina variants, catering to industries requiring precision abrasives for grinding, blasting, and refractory applications. While the company’s description emphasizes its technical capabilities in producing high-purity abrasives, it does not provide details on certifications, production capacity, or client references. Buyers are advised to confirm these specifics directly with the supplier for trade assurance.
