Import Bfa Brown Fused Alumina Powder — Buy in wholesale FOB from Supplier in China

BFA brown fused alumina powder is a precision-graded abrasive produced by electric arc fusion of high-grade bauxite, followed by controlled crushing and milling to produce specific particle size distributions. Zhengzhou Xinli Wear-Resistant Materials Co. Ltd. offers this material in micro-powder grades ranging from JIS 240# to 8000# and FEPA F240 to F1200, as well as national standard W-series grades from W63 down to W3.5. The powder retains the high hardness (Mohs 9.0) and toughness of macro-grain BFA while enabling fine finishing, precision casting, and high-surface-quality refractory coatings.

The reduction fusion process in electric arc furnaces produces large, dense crystals with high bulk density and stable inter-batch performance. For abrasive applications, the angular fracture pattern of BFA powder provides aggressive stock removal with controlled surface roughness. The supplier notes specific advantages including large crystal structure, batch stability, and superior polishing brightness compared to softer alternatives such as silica-based abrasives. Typical chemical composition for standard BFA powder includes Al2O3 of 95% minimum, with controlled limits on TiO2, Fe2O3, and SiO2 depending on application grade. The material is naturally low in free silica compared to alternatives, reducing respirable crystalline silica exposure in workplace environments.

Primary applications include grinding and polishing of stainless steel, optical glass, and stone; surface preparation of bicycle components, sewing machine parts, and medical instruments; and manufacture of coated abrasives, grinding wheels, and fibre-reinforced cutting discs. In refractory applications, fine BFA powder serves as plasticizer and matrix filler in castables and ramming mixes. Buyers are typically precision casting foundries, abrasive tool manufacturers, and advanced ceramics producers. Trade terms, MOQ, and exact pricing are not stated in the source and require direct confirmation with Zhengzhou Xinli Wear-Resistant Materials Co. Ltd. The company is located in Zhengzhou's Erqi District with harbor-tier trust classification.

Zhengzhou Xinli Wear-Resistant Materials Co. Ltd. maintains its registered address at Building 13, Wanda Plaza, Erqi District, Zhengzhou City, Henan Province, China. The company holds harbor-tier trust status within the supplier framework, with no response rate or average response time data currently available. Its product focus centres on wear-resistant and abrasive materials, specifically brown fused alumina in powder form across an extensive grade range from coarse micro-powders to ultra-fine 8000# specification. The Wanda Plaza address indicates a commercial office location in a central business district rather than an industrial manufacturing site.

The supplier profile provides no information about year of establishment, production capacity, employed staff count, annual revenue, or named domestic or international clients. No certifications such as ISO 9001, ISO 140274, or FEPA membership are mentioned. The company does not state whether it operates its own electric arc furnaces or sources intermediate BFA for further milling and classification. Buyers should request a company presentation, factory audit report, or video verification to assess actual production capabilities. The extensive grade list suggests either substantial classification capacity or trading relationships with multiple producers.
