Import Brown Fused Corundum Grain — Buy in wholesale FOB from Supplier in China

Brown Fused Corundum Grain from Zhengzhou Haixu Abrasives Co., Ltd. is an industrial abrasive manufactured by fusing high-purity alumina in an electric arc furnace, yielding a crystalline structure with exceptional hardness and thermal resistance. The material carries an Al2O3 content of 94.5-95.5%, placing it in the premium grade for fused alumina abrasives used in bonded wheels, coated abrasives, and blast cleaning operations. Sourced from Henan Province, a major Chinese production hub for refractory and abrasive minerals, this product is offered by an imported-tier supplier with harbor trust verification.

The grain structure is characterised by angular, tough crystals that fracture predictably under pressure, maintaining cutting efficiency across extended work cycles. Standard industry grades range from coarse macrogrits through microgrits, with typical particle sizes conforming to FEPA F-grain or P-grain standards depending on application. The brown colouration derives from residual titanium oxide (typically 2.5-3.5% TiO2) and traces of iron oxide, which act as crystal structure modifiers that enhance toughness compared to white fused alternatives. Buyers should specify the required grit distribution and any surface treatment, such as calcination or chemical washing, at the enquiry stage.

Primary applications include grinding wheel manufacture, abrasive blasting media, lapping compounds, and refractory castable aggregates where thermal shock resistance is critical. The product serves metalworking, automotive manufacturing, aerospace finishing, and construction ceramics sectors. Trade terms require direct confirmation with Zhengzhou Haixu Abrasives Co., Ltd. regarding MOQ, packaging format (typically 25 kg paper bags or 1-tonne bulk bags), and available Incoterms. The supplier's response rate is currently unrecorded, so buyers should allow additional time for quotation and sample provision.

Zhengzhou Haixu Abrasives Co., Ltd. is located at Room 1903, Yaxing Times Plaza, Erqi District, Zhengzhou City, Henan Province, China. The supplier holds an imported-tier classification on the platform with harbor trust-tier status. No response rate or average response time is recorded in the available profile data, which indicates buyers should anticipate variable communication speed and may need to follow up proactively on enquiries and sample requests.

The company operates from Zhengzhou, a central Chinese logistics and industrial hub with established abrasive mineral supply chains and access to rail and road freight networks serving Tianjin and Qingdao ports. The listing does not disclose factory ownership, production capacity, export licence details, or historical client base. Buyers are advised to verify business registration, ISO certification status, and quality management systems directly through the supplier before committing to trial orders. The product description references FEPA and GB/T standards compliance, but buyers should request current certificates of analysis and third-party test reports for specific batches.
