Neodymium magnets (NdFeB) deliver the highest energy density of any commercial magnet, enabling compact, high-torque designs with precise, repeatable performance. Trusted by engineers for motors, medical devices, robotics, and industrial sensors, these rare-earth magnets support tight dimensional tolerances for production-grade builds.

Choose from a wide range of grades, coatings, and geometries to meet demanding performance specifications—including high-temperature stability, corrosion-resistant finishes, and application-specific magnetization (axial, diametrical, multipole).

Frequently Asked Questions

What are neodymium magnets used for?

Neodymium magnets are ideal for prototypes that require high magnetic strength in a small space. They’re commonly used in sensors, motors, medical devices, robotics, magnetic couplings, and R&D projects.

What grades of neodymium magnets are available?

Neodymium magnets (NdFeB) are available in a wide range of grades, from N35 to N52, which indicate magnetic strength. For applications requiring performance in elevated temperatures or harsh environments, high-coercivity grades (often marked with suffixes like “H,” “SH,” “UH,” or “EH”) are available. These high-coercivity magnets resist demagnetization and maintain strength under higher operating temperatures — ideal for demanding prototypes and production designs.

Do neodymium magnets require a protective coating?

Yes. Neodymium magnets can corrode if left uncoated, so most come with a Nickel-Copper-Nickel (Ni-Cu-Ni) finish. For wet or medical environments, epoxy or parylene coatings are recommended to protect performance during testing and production. Selecting the proper magnet or coating all depends on your specific application. We’re here to help if you need further assistance, contact us.

Can you produce custom sizes, magnetization or coatings?

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
