Import Alnico Magnet Permanent Magnet — Buy in Bulk from Supplier in China

Hpmg Hangzhou Permanent Magnet Group manufactures Alnico permanent magnets at its facility in Hangzhou's Binjiang District, Zhejiang Province, China. The supplier cites over 10,000 available moldings and annual production capacity of 1,500 tons, with claimed global market share of 40 percent in their segment. These figures position the group as a volume producer, though buyers should independently verify capacity and market share claims. The Alnico alloy system used spans grades optimized for different magnetic circuits, with cast production dominant for larger geometries and sintered methods for precision components requiring tighter dimensional control.

The material composition centres on iron-aluminium-nickel-cobalt with potential copper and titanium additions, yielding magnetic properties that remain stable across temperature ranges destructive to rare-earth alternatives. Typical maximum energy product ((BH)max) ranges from 1.5 MGOe for isotropic grades to 9.0 MGOe for oriented high-cobalt formulations. Remanence values for common commercial grades sit between 7,000 and 13,500 Gauss. The supplier's extensive mold library suggests capability to produce arc segments, blocks, discs, rings, and custom geometries without lengthy tooling delays for standard shapes. Surface treatments typically include grinding to specified tolerances, with optional nickel plating or protective paint for corrosive environments.

Application sectors span electronics, automotive sensors, measurement instrumentation, aerospace systems, and educational apparatus where temperature stability and corrosion resistance matter more than maximum magnetic output. Buyers in motor manufacturing, magnetic separation equipment, and precision gauge industries represent the core procurement segments. Trade terms referenced include FOB and CIF, with flexible minimum order quantities stated. Exact MOQ, pricing, lead times, and payment instrument preferences require direct negotiation with Hpmg Hangzhou Permanent Magnet Group, as these operational specifics are not fixed in available listing data.

Hpmg Hangzhou Permanent Magnet Group operates from 6-1A #88 Jiangling Road, Binjiang District, Hangzhou City, Zhejiang Province, 310056, China. The supplier carries 'imported' tier classification and 'harbor' trust tier designation within platform records. Response metrics show 0.00 percent response rate with zero average response hours, indicating no tracked communication history through the platform interface. The Binjiang District location places the group in Hangzhou's established high-technology industrial corridor, with proximity to Ningbo-Zhoushan Port for export logistics.

The supplier profile highlights substantial production infrastructure, citing 1,500 tons annual capacity and extensive molding capabilities. No information is provided about founding date, ownership structure, factory floor area, employee count, R&D investment, or named clientele. The 40 percent global market share claim requires independent verification, as does the 10,000 molding count if critical to sourcing decisions. Buyers should determine whether Hpmg functions as integrated manufacturer or trading company, whether casting and heat treatment occur in-house or through subcontractors, and whether their quality system is certified to ISO 9001 or automotive standards like IATF 16949.
