Ferrite magnets
Chou Magnetics Co, Ltd. of Ningbo, Zhejiang, China manufactures ferrite magnets using strontium ferrite (SrFe12O19) as the base material. The catalogue lists Y30, Y35 and Y40 grades, each supplied in bulk form for industrial use. These ceramic magnets are known for strong resistance to demagnetisation and are priced per metric ton according to grade and size. The company provides the standard packaging of sealed steel drums for overseas shipment.
Strontium ferrite magnets typically exhibit a density around 5.0 g cm‑3 and a remanence (Br) of 0.30 - 0.35 T for the Y30 grade. Typical coercivity values lie near 200 kA m‑1, offering stable performance across a temperature range of - 40 °C to +250 °C. Industry standards often require dimensional tolerances of ±0.2 mm for discs and blocks, and surface finish classified as grade C. These characteristics make the magnets suitable for high‑volume motor and sensor assemblies where cost efficiency is critical.
Common buyers include automotive component manufacturers, consumer‑electronics OEMs and magnetic‑separation equipment producers. Chou Magnetics offers FOB and CIF terms, with payment by L/C or T/T, but exact MOQ and lead time must be confirmed directly. Interested importers should request a material test report confirming SrFe12O19 composition and the specific grade’s magnetic parameters.

Sourcing Ferrite Magnets from Chou Magnetics Co, Ltd. - China Import Guide
Before placing an order, verify that the grade code (Y30, Y35 or Y40) matches the magnetic performance required for your application. Request a material test report that confirms the SrFe12O19 composition and provides measured remanence and coercivity values for the specific batch. Because the supplier’s response rate is recorded as zero, confirm the contact person’s availability and ask for recent export documentation to ensure the company is actively trading.
Logistics should be clarified early; ask the supplier which Incoterms they can offer, such as FOB Ningbo port or CIF destination, and confirm the estimated lead time for production and shipment. Payment methods typically include L/C at sight or T/T, but the exact terms must be agreed before contract signing. Since the listing does not state a minimum order quantity, request the MOQ for the chosen grade and any tiered pricing structure.
Arrange a third‑party inspection at the factory or upon arrival at the port to verify magnetic properties and dimensional compliance. Ask for an ISO‑9001 quality‑management certificate or a specific test report that follows IEC 60404‑2 standards. Ensure that the packing list details the number of sealed steel drums, their weight, and the handling instructions, so that customs clearance proceeds without unexpected delays.
