Buy & Import Black Fused Alumina for Abrasives from Luoyang Zhongsen Refractory Co. Limited - Wholesale Supply

Black Fused Alumina for Abrasives from Luoyang Zhongsen Refractory Co. Limited is a synthetic corundum produced by fusing bauxite with a reducing agent in an electric arc furnace. The resulting black colour derives from controlled levels of ferro oxide and silicon oxide retained in the crystal structure. The supplier positions this material for abrasive rather than refractory end-use, with emphasis on moderate hardness, low heat generation during grinding, and adequate strength for metal and non-metal surface finishing.

The presence of Fe2O3 and SiO2 distinguishes black from white or brown fused alumina, lowering the macro-hardness while increasing toughness and shock resistance. Standard industry grades for abrasive applications range from F24 to F180 for coated and bonded products, with typical micro-hardness between 2000 and 2200 HV. The supplier notes suitability for stainless steel polishing, glass grinding, and grinding wheel manufacture, applications where reduced burn and loading are valued over maximum cutting speed.

Target buyers include manufacturers of resinoid grinding wheels, flap discs, sandpaper producers, and metal finishing job shops. Luoyang Zhongsen Refractory Co. Limited does not publish MOQ, price, packaging format, or lead time on the listing, so importers must request a formal quotation. Henan Province offers extensive abrasive industry infrastructure, but buyers should evaluate furnace capacity, quality control frequency, and export experience before committing to volume.

Frequently Asked Questions About Black Fused Alumina for Abrasives from Luoyang Zhongsen Refractory Co. Limited
Typical black fused alumina contains 5 - 10 percent Fe2O3 and 2 - 5 percent SiO2, though exact ranges vary by ore source and smelting control. The iron phase increases grain toughness and reduces fracturing under pressure, while the silica phase moderates hardness and lowers the threshold for workpiece burn. For stainless steel polishing, request a certificate of analysis from Luoyang Zhongsen specifying Fe2O3, SiO2, and free iron percentages to avoid contamination staining.

Sourcing Black Fused Alumina for Abrasives from Luoyang Zhongsen Refractory Co. Limited - China Import Guide

Before contracting Luoyang Zhongsen Refractory Co. Limited, verify corporate existence through the Henan Administration for Industry and Commerce, and request a proforma invoice on company letterhead with full banking details. Ask for two recent customer references in your region, and confirm the supplier's export licence status. If possible, commission a factory audit focused on furnace control, laboratory capability, and environmental compliance before committing to a container load.

Shipping from Luoyang typically routes through Lianyungang or Qingdao port. Abrasive grain is classified as non-dangerous cargo, but importers should confirm HS code 2818.10 or local equivalent with their customs broker. The supplier has not stated Incoterms, so negotiate FOB, CFR, or CIF terms explicitly, and clarify who bears fumigation, palletisation, and export declaration costs. For payment, consider a documentary letter of credit for the first transaction, transitioning to open account only after established trust.

On receipt, inspect container seals and packaging integrity before unloading. Draw a representative sample using coning and quartering or a mechanical sampler, and submit it for independent sieve analysis, chemical assay, and bulk density determination. Compare results against the supplier's certificate of analysis. Retain one sealed sample as an arbitration reference. Document any discrepancy immediately, with photographs and weighbridge records, to support insurance or contractual claims.
