Uses for our rare earth disc magnets

This 20mm x 3mm Neodymium Rare Earth magnet has a Gold plating, providing a range of benefits unique to the properties of this coating. Medical and therapeutic product manufacturers also use Gold plated magnets as they are relatively hypoallergenic compared to the more common Nickel plating. Gold plated magnets are also popular for applications where aesthetics are important. Craftspeople, hobbyists and artists use Gold plated magnets as they have a more desirable finish and add a touch of luxury and elegance to a finished object. Gold coated magnets are still susceptible to rust when exposed to the elements or damage from their environment. If you need to ensure that your gold magnet does not rust, you may want to consider applying a sealant which will extend the lifespan of the coating, but may reduce the pull force.
