Disc Epoxy Coated Magnets are typically rare-earth magnets, often made from neodymium, which are coated with an epoxy resin to provide protection against corrosion and physical damage. Here are some common technical parameters you might find for these magnets:

• 1. Material: Neodymium-Iron-Boron (NdFeB)
• 2. Coating: Epoxy
• 3. Shape: Disc
• 4. Dimensions: Diameter and thickness (e.g., 10 mm diameter x 2 mm thickness)
• 5. Magnet Grade: Ranges from N35 to N52 (indicating the strength of the magnet, with N52 being the strongest commonly available grade)
• 6. Magnetic Properties: – Remanence (Br): Indicates the residual magnetic field. Typically ranges from 1.1 to 1.5 Tesla. – **Coercivity (Hcb)**: The resistance to demagnetization. Typically ranges from 836 to 923 kA/m. – Intrinsic Coercivity (Hcj): The resistance to demagnetization under the influence of an opposing magnetic field. Typically ranges from 955 to 2000 kA/m. – Maximum Energy Product (BHmax): The density of magnetic energy. Typically ranges from 280 to 422 kJ/m³.
• 7. Operating Temperature: Maximum operating temperatures can range from 80°C to 200°C depending on the grade and specific composition of the magnet.
• 8. Density: Approximately 7.5 g/cm³
• 9. Magnetic Pole Orientation: Axially magnetized (North and South poles are on the flat faces of the disc)
• 10. Epoxy Coating Thickness: Typically around 10-20 micrometers.
