Import Binic Abrasive Zirconia Alumina Flap Disc — Buy in wholesale FOB from Supplier in China

Shanghai Binic Industrial Co., Ltd manufactures zirconia alumina flap discs with a composite abrasive of ZrO2/Al2O3 mounted on fiberglass backing, engineered for aggressive stock removal on stainless steel, alloy, and carbon steel workpieces. Standard diameters span 115mm to 180mm (4 to 6 inches), with grit sizes from 40 to 120. The source description confirms availability in 115mm, 125mm, 150mm, and 180mm variants, alongside ceramic alumina and silicon carbide alternatives for specialised applications. These discs deliver 2-3 times longer service life than standard aluminium oxide equivalents, a critical metric for high-volume industrial buyers.

The zirconia alumina grain structure self-sharpens during operation, maintaining cut rate as the abrasive wears, while the fiberglass backing plate provides rigidity and vibration dampening at peripheral speeds typical of angle grinders. Standard thickness and flap count follow industry norms for each diameter, though the exact flap count per disc is not supplier-specified and should be confirmed directly. The backing is phenolic resin bonded to the flaps, a standard construction method that resists loading on gummy materials like stainless steel. Buyers should verify whether the discs are European standard (M14 or M22) or threaded for specific spindle configurations, as this affects compatibility with existing equipment.

Fabrication shops, shipyards, and automotive component manufacturers represent the core demand for these discs, particularly in welding preparation, surface finishing, and deburring operations where rapid material removal precedes final finishing stages. The 40-grit and 60-grit variants suit heavy stock removal, while 80-grit through 120-grit serve blending and pre-polish work. Industrial buyers should confirm minimum order quantities, packaging configurations (typically bulk carton or plastic hub protectors), and whether Shanghai Binic Industrial Co., Ltd provides test reports for vibration balance or maximum operating speed. Lead times and Incoterms are not stated in the listing and require direct supplier negotiation.

Shanghai Binic Industrial Co., Ltd is headquartered at Unit 706, Building 25, No. 8633 Zhongchun Road, Shanghai 201101, China, placing it within the city's industrial belt with access to port infrastructure via Shanghai Port. The supplier holds a 'harbor' trust tier designation, indicating a baseline verification status on the platform. The response rate is recorded at 0.00 percent with zero average response hours, which suggests either a new listing, inactive account, or data capture issue rather than necessarily indicating non-operation. Buyers should verify current responsiveness through direct contact before relying on quoted availability.

The listing presents Shanghai Binic Industrial Co., Ltd as a specialised source for coated abrasives, with particular emphasis on zirconia alumina flap discs for metalworking applications. No employee count, annual revenue, factory certification, or years in operation is provided in the source data, and none should be assumed. The product range extends beyond zirconia alumina into ceramic alumina and silicon carbide flap discs, indicating some breadth in bonded abrasive manufacturing. Buyers are advised to request ISO 9001 or OSA certification documentation, factory audit reports, and sample batch testing results directly from the supplier, as these are not confirmed in the listing.
