Import Brown Fuzed Aluminum/Brown Corundum — Buy in Bulk from Supplier in China

Brown Fuzed Aluminum from Luoyang Huayun Import & Export Co., Ltd. is a fused alumina abrasive produced by electric arc melting of calcined bauxite, yielding a crystalline structure with pronounced toughness and thermal stability. The supplier specifies a maximum TiO2 content of 3.00%, a refractoriness of 1980 °C, and a true density of at least 3.90 g/cm³, with a melting point of 2050 °C. These figures indicate a standard industrial-grade brown corundum suitable for applications where moderate toughness and consistent heat resistance are required over extreme friability.

The material's physical properties derive from its fused microstructure: a solid solution of α-alumina with dispersed titaniferous phases that inhibit crystal growth and enhance fracture resistance. Standard brown fused alumina typically exhibits a Knoop hardness of 1900-2000 and is supplied in angular grains from macrogrit sizes down to microgrit powders. Luoyang Huayun sources from or operates within Henan Province, China's principal region for both bauxite mining and fused alumina production, though the listing does not confirm vertical integration or factory ownership details.

Industrial consumers use this product in grinding wheel manufacture, abrasive blast cleaning, wear-resistant refractory linings, and lapping pastes for hardened steels and ceramics. The construction, metal fabrication, and glass processing sectors represent typical end-markets. Buyers must contact Luoyang Huayun Import & Export Co., Ltd. directly to confirm available grit distributions, packaging configurations, minimum order quantities, and current pricing, as these operational specifics are not provided in the source data.

Luoyang Huayun Import & Export Co., Ltd. is registered at Room 707, Block C, World Trade Center, Kaiyuan Road, Luoyang 471003, China. The supplier is classified as an imported-tier participant with harbor trust-tier status on the platform. No response rate or average response time data is available, suggesting buyers should establish direct communication channels and set clear expectations for quotation turnaround and sample dispatch timelines.

The company is based in Luoyang, a city in western Henan Province with historical significance in refractory materials and access to regional rail networks connecting to Zhengzhou and coastal ports. The listing does not disclose manufacturing assets, annual throughput, employee count, export licence numbers, or client references. Buyers should conduct independent due diligence on company registration, tax status, and any claimed quality certifications before advancing beyond initial enquiry. The product description mentions ISO and SGS compliance, but current certificate validity must be verified directly with the supplier and, where possible, with the issuing bodies.
