10mm x 6mm x 3mm Neodymium Arc magnets

These customized powerful heat resistance  high adhesive force permanent compact square NdFeB Magnets are designed for industrial applications, especially in making energy-efficient electric motors and generators. Their curved shape allows them to fit smoothly around the rotor, helping to create a strong and steady magnetic field. This improves motor performance and helps save energy. Commonly used in industries like automotive, robotics, and clean energy, these magnets support systems that need high torque and efficiency.  Powerful high adhesive force permanent stable  compact square NdFeB Magnets also play a key role in industrial machinery and automation, helping equipment run reliably and last longer, an important benefit for modern manufacturing.

Magnet Grade: N42

N52 neodymium magnets offer some of the strongest magnetic power available, with an energy rating of up to 52 MGOe. As one of the highest grades, they are ideal for projects that need extra-strong magnetism. Their powerful performance makes them a reliable choice for demanding applications where maximum strength is essential.

Surface Finish: Ni-Cu-Ni Coating

These tailor-made powerful high adhesive force fast response  permanent compact square NdFeB Magnets are finished with a durable triple-layer Ni-Cu-Ni (Nickel-Copper-Nickel) coating that enhances corrosion resistance and maintains a clean, professional look. This layered shield protects the magnet’s core from oxidation and wear in mildly humid environments, making them suitable for long-term use in a range of settings. For more aggressive environments, epoxy or other advanced coatings may offer enhanced protection.
