Import Alnico Magnets — Buy in Bulk from Supplier in China

Alnico magnets from China Rare Earth Magnet Ltd. are permanent magnets composed of aluminium, nickel and cobalt, delivering stable magnetic performance in demanding environments. The supplier’s material maintains its properties at operating temperatures up to 550 °C, a key advantage for applications exposed to heat, and exhibits strong resistance to demagnetisation under thermal stress. Shapes offered include discs, blocks, rings and custom forms to match specific engineering requirements.

The alloy’s typical composition is 8 - 12 % aluminium, 14 - 25 % nickel, 24 - 32 % cobalt, with iron and copper balancing the mix, which produces high remanence and moderate coercivity. Standard grades such as Alnico 5 and Alnico 8 are common in industry, with Alnico 5 offering a good balance of strength and cost, while Alnico 8 provides higher coercivity for applications needing resistance to external demagnetising fields. Surface treatments like nickel plating are typical to enhance corrosion resistance in humid or aggressive conditions.

These magnets are widely used in automotive sensors, electric motors, loudspeakers, and industrial holding systems where reliability at elevated temperatures is critical. Buyers typically source them in bulk for OEM assemblies, with packaging in cartons or palletised boxes to prevent mechanical damage. Confirming exact grade, dimensional tolerances and magnetic performance curves with the supplier is essential before ordering for precision applications.

China Rare Earth Magnet Ltd. operates from Room 705-707, Ruisi Center, No.9030 Shenzhen 518053 Guangdong China, where it specialises in the supply of rare earth and alnico permanent magnets for industrial applications. The company is classified as an imported-tier supplier with a harbor trust tier, indicating it meets baseline verification standards for export readiness.

The supplier’s profile does not state a minimum order quantity, lead times, or specific certifications beyond the mention of ISO and SGS standards in the product description. There is no recorded response rate or average response time, so buyers should expect to initiate contact directly to confirm technical details, availability, and trade terms before proceeding with an order.
