Neodymium magnets are prone to corrosion and surface damage if left uncoated. Coatings protect the magnet material from oxidation, chemicals, and wear—ensuring long-term performance and dimensional stability.

Consider your environment (dry, humid, chemical exposure), mechanical stresses (abrasion, impact), electrical needs (conductive or insulated), and any biocompatibility requirements. Our Magnet Coating Specifications chart can help guide your selection.

Many coatings, including Parylene and Gold, are compatible with cleaning and sterilization processes. For critical medical or food-grade applications, confirm compatibility with your process before production.

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.
