BFA Brown Fused Alumina for lapping
Brown Fused Alumina for lapping from Zhengzhou Haixu Abrasives is a synthetic aluminium oxide abrasive produced by smelting bauxite and anthracite coal in electric-arc furnaces above 2000 degrees Celsius. The material contains a minimum 92% Al2O3, with controlled limits of 2% SiO2, 2% Fe2O3 and 4% TiO2. It is supplied in micro powder grades from F230 up to F1200 under FEPA standards, plus JIS grades from #240 to #2000, and is packaged in 25kg bags or 1MT bulk sacks for industrial export.
The crystal structure offers high purity, good crystalline liquidity and low linear expansion, with a Mohs hardness of 9.0 and specific gravity between 3.6 and 3.9 g/cm3. Bulk density ranges from 1.53 to 1.99 g/cm3 depending on grain size and packing. The melting point is 2250 degrees Celsius and maximum service temperature reaches 1850 degrees Celsius, giving it corrosion resistance and mechanical stability under severe lapping conditions. Typical lapping-grade BFA from Chinese producers is characterised by consistent grain angularity and minimal friability, which controls finish quality on precision components.
Primary applications include precision grinding for optical lenses, monocrystalline silicon wafers, glass and jadeware, plus lapping and micro-blasting in semiconductor and aerospace manufacturing. The material also serves in bonded and coated abrasives, surface preparation, thermal spraying and wear-resistant flooring for highways, airports and docks. Buyers are typically precision tool manufacturers, optical component fabricators and semiconductor polishing houses. Trade terms, lead times and exact MOQ should be confirmed directly with Zhengzhou Haixu Abrasives, as these are not stated in the listing data.

Zhengzhou Haixu Abrasives Co., Ltd. is located at Room 1903, Yaxing Times Plaza, Erqi District, Zhengzhou City, Henan Province, China. The supplier is classified under an imported tier with harbour trust status. The response rate is recorded at 0.00% and average response time is zero hours, which indicates no response history is available through the platform. The company profile does not state year of establishment, factory size, headcount, revenue, or client references.
The listing focuses on brown fused alumina abrasives for lapping, polishing and precision finishing applications, with product data covering chemical composition, physical properties and grade ranges. What the profile does not contain is equally notable: no certifications are listed, no production capacity is given, and no export destinations are named. Buyers should treat the absence of these details as gaps to verify during direct negotiation, and should request documentation of quality control procedures and any ISO or factory audit certificates that may exist.
Brown Fused Alumina (BFA) is a high-grade aluminum oxide abrasive manufactured from bauxite smelted at temperatures exceeding 2000 degrees Celsius in electric-arc furnaces. This lapping-grade BFA features consistent grain structure and high hardness, making it ideal for precision lapping, polishing, and superabrasive tool production in aerospace, automotive, and semiconductor industries. Widely traded globally with major supply origins in China, India, and Brazil, BFA is classified under artificial corundum and supplied in grit sizes ranging from F230 to F1200 for lapping applications, packaged in 25kg bags or 1MT bulk sacks for industrial export.

Sourcing BFA Brown Fused Alumina for Lapping from Zhengzhou Haixu Abrasives Co., Ltd. - China Import Guide
Before ordering, verify that Zhengzhou Haixu Abrasives can provide batch certificates of analysis with actual test values rather than guaranteed maxima or minima alone. Confirm the specific FEPA or JIS grade nomenclature they use, as Chinese producers sometimes apply internal standards that diverge from FEPA-JIS particle size distributions. Ask for references from buyers in semiconductor or optical industries, or request a small trial shipment to evaluate cutting rate and surface finish on your substrate.
Logistics from Zhengzhou, Henan Province, typically route through Qingdao, Tianjin or Shanghai for ocean export. Confirm the port of loading, Incoterms offered and whether the supplier handles export customs clearance or requires a freight forwarder. Lead time, payment terms and letter of credit acceptance are not stated and must be negotiated directly. For bulk orders, consider requesting container loading supervision to verify bag counts and condition before sealing.
On arrival, inspect packaging integrity for moisture ingress or broken bags, and retain samples from multiple bags for independent sieve analysis and chemical verification. Test magnetic content with a standard separator, as elevated iron levels cause scratch defects in precision lapping. Retain certificates of analysis and compare against incoming inspection results; any significant deviation should trigger a supplier corrective action request before committing to full production volumes.
