The Ningbo Chiyue ring magnet is a permanent magnet manufactured from samarium cobalt alloy SmCo S28G. It is supplied in a toroidal shape that provides a uniform magnetic field around the ring. The material offers a maximum operating temperature of 300°C and excellent corrosion resistance. The magnet is intended for magnetic coupling, motor assemblies and sensor applications.
SmCo S28G belongs to the high-temperature rare-earth class, delivering a typical magnetic energy product around 20 MGOe and coercivity near 800 kA/m. Compared with neodymium magnets, it retains its performance at elevated temperatures without significant loss of flux density. Standard industry practice packages these magnets in anti-static cardboard with foam inserts to protect against mechanical shock. Dimensional tolerances are usually maintained within ±0.1 mm for inner and outer diameters.
Engineers in the automotive, aerospace and renewable-energy sectors commonly integrate these ring magnets into actuators and rotary devices. Importers should request certification such as ISO 9001 or SGS to confirm material conformity, as the listing does not specify them. Trade is typically arranged on FOB or CIF terms, and the supplier can accommodate bulk shipments once the order details are finalised.

Before placing an order, verify the exact magnetic grade, dimensions and any surface‑treatment specifications with Ningbo Chiyue. Request the material test report, corrosion‑resistance data and, if required, an ISO 9001 certificate to confirm compliance with your quality standards. Clarify whether the supplier can supply the magnet in the required batch size and confirm any custom tolerances.
Discuss the preferred Incoterm - FOB Ningbo port or CIF to your destination - and confirm the lead time once the order quantity is finalised. Payment terms are usually negotiated as a TT advance or a letter of credit, but the exact arrangement must be agreed directly with the supplier. Ensure that freight forwarders are aware of the anti-static packaging to avoid handling damage during transit.
Arrange an independent third‑party inspection at the factory or upon arrival to validate magnetic performance and dimensional accuracy. Request a final test report covering magnetic energy product and coercivity according to ASTM B221. Maintaining proper documentation, such as the certificate of origin and customs paperwork, will smooth the import clearance process.
