Import Black Fused Alumina — Buy in wholesale FOB from Supplier in China

Ningxia Huiheng Activated Carbon Sales Co., Ltd. offers black fused alumina with a stated aluminium oxide content of 70-75 percent, placing it toward the higher purity range for this dark abrasive grade. The material is produced by high-temperature fusion, a process that forms alpha-alumina crystals from bauxite feedstock with controlled iron additions. This supplier, based in Ningxia Hui Autonomous Region, positions the product for grinding, cutting, and polishing operations where thermal shock resistance is valued. The exact fusion method, furnace type, and raw material source should be confirmed directly with the supplier, as these influence consistency and trace element profiles. Buyers should note that the company name suggests carbon products as a primary business line, with fused alumina potentially a secondary or traded product.

The 70-75 percent Al2O3 content distinguishes this offering from lower-grade black fused alumina, with implications for hardness, cutting rate, and suitability for specific substrate materials. Standard black fused alumina with this composition typically contains 7-10 percent Fe2O3 and 2-4 percent TiO2, though the source only specifies the alumina figure. The material's toughness, indicated as a key property, derives from the solid solution of titania in the alumina lattice and the intergranular iron phases formed during cooling. Available forms likely include angular grit for bonded abrasives and refractories, and micro-powders for coated applications, though specific FEPA or ISO gradings are not listed and must be requested from the supplier.

Applications cited include sandblasting, refractory manufacturing, and advanced ceramics, with the automotive, metalworking, and construction sectors named as target industries. The supplier indicates availability under T/T and L/C payment terms, with flexible MOQ, though no figures are provided and should be negotiated directly. For refractory applications, buyers should verify refractoriness under load, permanent linear change, and cold crushing strength. For blasting, specify surface profile requirements and substrate material to match grain size and hardness. The Ningxia location offers rail access to Tianjin and Qingdao ports, with potential advantages for bulk shipment logistics compared with more congested eastern manufacturing regions.

Ningxia Huiheng Activated Carbon Sales Co., Ltd. is registered in Huinong District, Hongguozi Town, Ningxia, with postal code 753000. The company name and location indicate primary specialisation in activated carbon products, with black fused alumina representing either a manufactured item using similar high-temperature processing equipment or a traded product line. The 'harbor' trust tier designation provides limited assurance, and the zero percent response rate with zero average response hours suggests minimal platform-mediated communication history. Buyers should establish direct contact through the provided address or alternative channels before assuming trading relationship viability.

No founding date, registered capital, employee count, production capacity, or named clientele appears in the source data. The supplier does not claim manufacturing credentials specific to fused alumina, and buyers should determine whether the company operates its own fusion furnaces or sources from third-party producers in Ningxia or neighbouring regions. Ningxia has industrial infrastructure for ferroalloys and carbides, but is not a primary fused alumina production centre compared with Henan, Guizhou, or Shandong. Due diligence should include verification of export licence scope, environmental compliance permits for high-temperature fusion operations, and inspection of quality management documentation relevant to abrasive materials rather than carbon products alone.
