Chou Magnetics Co, Ltd. supplies alnico magnets as permanent magnets made from an aluminum-nickel-cobalt-iron alloy, with typical compositions of Al 8 - 12%, Ni 20 - 30%, Co 35 - 40%, and Fe as the balance. The company offers both cast and sintered forms, including grades such as Alnico 3, Alnico 5, and Alnico 8, which are selected based on the required flux density and temperature stability. These magnets are particularly valued for their ability to retain magnetic properties in high-temperature environments up to 500°C.
Sintered alnico magnets provide finer grain structures and tighter dimensional tolerances compared to cast variants, making them suitable for precision applications like guitar pickups and small sensors. The supplier’s typical production process adheres to industry standards for magnetic materials, with common post-processing treatments such as grinding, polishing, or coating to meet specific buyer requirements. Aluminum-nickel-cobalt alloys are mature in the market, with well-documented performance in demagnetization-resistant applications.
Industrial buyers source these magnets for use in electric motors, aerospace instruments, and holding systems where reliability under thermal stress is essential. The supplier’s location in Ningbo, Zhejiang, positions it within a key export hub for magnetic materials, facilitating efficient shipping and trade logistics. For bulk orders, confirm the availability of specific grades and forms, as well as the supplier’s capacity to meet your volume and delivery timelines.

Before placing an order, confirm the exact grade and form (cast or sintered) of the alnico magnets, as these factors determine their suitability for your application. Request detailed magnetic property data, including remanence and coercivity, to ensure the magnets meet your technical specifications. For critical applications, ask for third-party certifications or test reports to validate performance claims.
Discuss logistics early, including lead times, Incoterms (e.g., FOB Ningbo), and packaging requirements. Alnico magnets should be packed in non-magnetic materials to prevent demagnetization during shipping. For bulk orders, clarify whether the supplier can accommodate your preferred shipping method and any special handling needs for fragile or precision components.
Implement a quality control plan that includes dimensional checks, surface inspections, and magnetic performance testing. For high-value or high-risk contracts, consider third-party inspection services to verify compliance with your specifications. Ensure all documentation, such as material certifications and test reports, is provided in English to facilitate customs clearance and internal audits.
