Zinc Coating

Zinc (Zn) Plating: Zinc plating is another popular surface treatment used for neodymium magnets, particularly in environments where cost-effectiveness and moderate corrosion resistance are required. In this process, a thin layer of zinc is electroplated onto the magnet's surface, providing basic protection against oxidation and wear. Zinc plating is a "self-sacrificing" coating, meaning when the material corrodes, the outside turns white, creating a durable layer of protection. It is often used for automotive sensors, switches, and other industrial applications
