Gongyi Qingyun Refractories Co., Ltd. produces black fused alumina powder through electric arc furnace smelting of bauxite with iron oxide and trace additives in Henan Province, China. The material contains 85-95% Al2O3 with Fe2O3, TiO2 and SiO2 as the principal impurities, giving it moderate hardness and good toughness compared to brown or white fused alumina variants. The supplier uses a dumping-type electric arc furnace process to produce massive black fused alumina blocks, which are then processed into sand and powder fractions.
The lower alumina content relative to brown fused alumina (typically 95% plus Al2O3) and white fused alumina explains the cost advantage of this grade, since alumina is the most valuable component in the fused alumina family. The dark colouration derives from higher iron content introduced during smelting, and the sharp, angular grain morphology is characteristic of all electro-fused abrasives. Typical applications include sandblasting, water jet cutting, coated abrasives production, and surface finishing of soft metals, non-ferrous materials and stone surfaces.
Buyers in foundries, metalworking shops and construction material manufacturing source black fused alumina powder in bulk bags or drums for high-volume abrasive operations where cost efficiency matters. The material is particularly suited to applications where the extreme hardness of brown or white alumina is unnecessary or where surface finish requirements are less critical. Importers should confirm packaging specifications, exact Al2O3 grade and batch consistency directly with Gongyi Qingyun Refractories Co., Ltd., as the listing does not state guaranteed tolerances or specific mesh sizes available.

Buyers should treat all commercial terms, including exact MOQ, pricing structure, and lead times, as unverified and requiring direct confirmation with the supplier.
Black Fused Alumina Powder is a high-performance industrial abrasive manufactured through electric furnace smelting of bauxite ore, resulting in dark-colored sharp-edged grains ideal for grinding soft metals, non-ferrous materials, and stone surfaces. Widely used in sandblasting, water jet cutting, coated abrasives, and surface finishing operations, this material offers excellent cost-efficiency for high-volume abrasive applications. As a key commodity in the global abrasives trade, black fused alumina powder is exported in bulk bags or drums with typical purity grades of 85-95% Al2O3, serving foundries, metalworking shops, and construction material manufacturers worldwide.

Before placing an order with Gongyi Qingyun Refractories Co., Ltd., verify the exact Al2O3 specification for your required grade, as the 85-95% range covers multiple quality tiers. Request a recent certificate of analysis showing Fe2O3, TiO2 and SiO2 percentages, and confirm that the supplier can meet your target mesh size with acceptable batch-to-batch variation. Given the zero percent response rate shown, establish direct communication channels and test responsiveness before committing to a large shipment, and consider requesting a small trial lot to evaluate friability and cutting performance against your incumbent abrasive supply.
Confirm shipping arrangements from the Chinese port of departure, available incoterms, and whether the supplier handles export clearance or requires your nominated freight forwarder. Bulk abrasive powder shipments typically move in 20-foot or 40-foot containers, and proper stowage to prevent moisture ingress is critical. Ask about typical production lead times from order confirmation, seasonal variations in furnace scheduling around Chinese New Year, and whether the supplier maintains finished goods inventory for faster dispatch. Payment terms, including advance deposit percentages and balance settlement methods, should be negotiated and documented in the sales contract.
Implement incoming quality inspection upon arrival, including sieve analysis to verify grain size distribution, chemical assay for Al2O3 content, and visual inspection for colour uniformity and foreign matter contamination. Retain samples from each batch for future reference and performance correlation. Ensure your handling and storage facilities protect the powder from moisture, which can cause caking and flow problems in pneumatic conveying systems. Document any discrepancies immediately and agree dispute resolution procedures with the supplier before the first shipment departs.
