Ltd. is produced by fusing quality bauxite ore in an electric arc furnace, resulting in a material composed predominantly of Al2O3 with iron oxide impurities. This gives the abrasive its black color and balanced properties of hardness and durability, making it a cost-effective choice for surface preparation, deburring, and refractory applications.
The abrasive’s chemical composition typically includes Al2O3 as the primary component, with Fe2O3 and trace impurities contributing to its matte appearance and high strength. Standard industry grades for black fused alumina often range from 16 to 220 mesh, with coarser grits used for cutting and blasting and finer grits for polishing and lapping. The supplier’s material is noted for its reliability in applications requiring wear resistance.
This black corundum is widely used in foundries, steel processing, and metal fabrication industries, particularly in markets like Southeast Asia, the Middle East, and Eastern Europe. Its versatility extends to abrasive blasting, grinding wheels, and refractory castables. Zhengzhou Xinli Wear-Resistant Materials Co. Ltd. offers the product for bulk trade, with terms and packaging details to be confirmed directly.

Before placing an order, verify the exact Al2O3 and Fe2O3 content with Zhengzhou Xinli Wear-Resistant Materials Co. Ltd., as these influence the material’s hardness and suitability for your application. Request a material safety data sheet (MSDS) and test reports to confirm compliance with industry standards for abrasives or refractories.
Clarify logistics details, including lead times, Incoterms (e.g., FOB Zhengzhou), and payment terms, as these are not provided in the listing. Discuss packaging options (e.g., 25 kg or 50 kg bags) and moisture protection measures to ensure the product arrives in optimal condition. Confirm the supplier’s ability to handle bulk shipments and any special loading requirements.
Conduct quality checks for grain size distribution, moisture content, and foreign matter, as these can impact performance. Request samples for trial runs in your specific application, such as surface preparation or refractory casting. Ensure the supplier provides inspection certificates and documentation for traceability. For critical applications, consider third-party testing to validate the material’s properties.
