Neodymium Disc Magnets
Gold coated Neodymium magnets are slightly more corrosion resistant than standard nickel coated ones. This can help to extend their working life in certain circumstances and can make them a more economical proposition in the long term. As gold is a soft and malleable metal, it does not tolerate abrasive forces well, so applications that subject the magnet to constant impact or rubbing should be avoided. Other applications sometimes benefit from the electrically conductive capabilities that gold coatings present, making them suitable for use in electrical devices, alarms, gauges and for scientific purposes.
The visually attractive nature of Gold coatings appeals to jewellery makers and fashion designers who use magnets to embellish their work and make it more practical to use. Artisans involved in creating small production, home-based items also find these magnets can give their designs a unique and original quality. Gold is also regarded as a harmless and non-toxic natural element and for this reason many Naturopaths and those who believe in the healing power of magnetic therapy choose Gold coated magnets for use on their clients. Neodymium magnets are small yet powerful and these factors have led to their inclusion in many modern day technologies and innovations where reduced size and greater capacity is the prevailing objective.
Gold-coated magnets can still rust when exposed to moisture or environmental damage. To protect your gold magnet from corrosion, consider applying a sealant to extend the life of the coating. However, keep in mind that this may slightly reduce the magnet’s overall pull strength.

Surface Treatment
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Magnetic Properties
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
