Disc Magnet
The Disc Magnet from Ningbo Chiyue Import & Export Co., Ltd. is a Samarium Cobalt (SmCo) magnet of Grade S28G, measuring 16 mm in diameter and 5 mm in thickness, axially magnetized with no protective coating. It delivers a high energy product with minimal flux loss over temperature, making it suitable for applications requiring stable magnetic performance in extreme environments. This is not a generic ferrite magnet but a rare earth component engineered for precision assemblies.
Samarium Cobalt S28G offers a maximum energy product of 28 MGOe and retains over 90% of its magnetic strength up to 300°C, far exceeding neodymium magnets in thermal stability. The uncoated surface is typical for this grade, as SmCo is inherently corrosion-resistant and does not require plating. The material composition includes approximately 25% samarium and 75% cobalt, with trace additions of iron and copper to optimize coercivity. Standard production tolerances are ±0.1 mm on diameter and height.
This magnet is used in aerospace actuators, high-speed motor rotors, medical imaging sensors, and precision positioning systems where temperature cycling or exposure to moisture would degrade other magnet types. Buyers include OEMs in automotive sensor manufacturing, robotics integrators, and defense contractors. The product is supplied in packs of 8 units, typically packed in anti-static foam within rigid plastic trays. MOQ and lead time are not listed and must be confirmed directly with the supplier.
| Material | Samarium Cobalt (SmCo), Grade S28G |
| Shape | Disc |
| Diameter | 16 mm ±0.1 mm |
| Thickness | 5 mm ±0.1 mm |
| Magnetization Direction | Axial |
| Coating | None |
| Maximum Energy Product | 28 MGOe (typical for S28G) |
| Remanence (Br) | 0.95 to 1.00 T (typical) |
| Coercivity (HcJ) | ≥ 2000 kA/m (typical) |
| Operating Temperature Range | -50°C to +300°C (standard for SmCo S28G) |
Ningbo Chiyue Import & Export Co., Ltd. is a trading company based in Ningbo, Zhejiang, engaged in the export of magnetic components and industrial hardware.

Sourcing Disc Magnet from Ningbo Chiyue Import & Export Co., Ltd. - China Import Guide
Before ordering, confirm the exact grade designation (S28G) and request a material certificate with magnetic properties tested per IEC 60404-5. Verify that the dimensions are measured with calibrated micrometers and that the magnetization direction is marked. Do not accept magnets without traceable batch numbers or test data. Ensure the supplier provides a declaration of conformity for RoHS and REACH compliance.
Lead time for SmCo magnets typically ranges from 3 to 6 weeks due to material sourcing and magnetization processes. Shipping is usually FOB Ningbo port, with options for air freight for urgent orders. Incoterms like CIF or DDP are negotiable but not standard. Payment terms are commonly 50% advance and 50% before shipment. Buyers should confirm packaging specifications for international transport, especially for air freight regulations on permanent magnets.
Quality verification should include a gauss meter reading at the surface, dimensional inspection with digital calipers, and a visual check for surface defects or oxidation. Request a magnetic flux map if used in precision assemblies. Documentation must include the grade, batch number, test results for Br, HcJ, and operating temperature limits. Avoid accepting shipments without these documents, as they are critical for certification in aerospace or medical applications.
