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

Alnico magnets from Hpmg Hangzhou Permanent Magnet Group are permanent magnets engineered from aluminum, nickel and cobalt alloys, delivering high magnetic strength and exceptional thermal stability. These magnets retain their magnetic properties at elevated temperatures, often exceeding 500 degrees Celsius, making them suitable for applications where heat resistance is critical. The supplier’s range includes multiple grades such as Alnico 5, known for its balanced coercivity and remanence, and Alnico 8, which offers higher coercive force for demanding environments.

The material composition typically includes 8-12% aluminum, 15-26% nickel, 5-24% cobalt, with the balance being iron, plus minor additions of copper or titanium to enhance properties. Standard shapes include bars, discs, rings and horseshoes, with typical tolerances of ±0.1 mm for machined parts. Surface treatments such as nickel plating or epoxy coating are applied to prevent corrosion, a common requirement in automotive and aerospace applications where long-term durability is non-negotiable.

These magnets are widely used in sensors, motors, generators and loudspeakers, particularly in industries like automotive, medical devices and renewable energy. Buyers source them in bulk under FOB or CIF terms, with packaging typically in cartons or pallets to prevent demagnetization during transit. Custom designs are available to meet specific dimensional or performance criteria, with the supplier’s 35 years of manufacturing experience ensuring adherence to stringent quality standards.

Hpmg Hangzhou Permanent Magnet Group operates from 6-1a #88 Jiangling Road, Binjiang District, Hangzhou City, Zhejiang Province, China. The company specializes in the production of permanent magnets, with a focus on Alnico alloys, leveraging over three decades of manufacturing expertise. Its facility is positioned to serve both domestic and international markets, catering to industries that demand high-precision magnetic components.

The supplier is classified under the imported tier with a harbor trust tier, indicating a baseline level of verification. While the response rate and average response hours are currently not recorded, the company’s long-standing presence in the magnet industry suggests a capacity to handle bulk and custom orders. The supplier’s profile highlights a commitment to quality, with products designed to meet stringent industry standards, though specific certifications are not explicitly confirmed in the available data.
