The beauty of gold is not just for decoration and adornment. Gold-coated Neodymium magnets have truly remarkable qualities that make them not just sleek, but extremely useful. These rare earth discs have applications in jewellery making, fashion design and even magnetic health therapy, where the inert nature of gold is thought to be less likely to cause allergic reactions or be rejected by the body.
Some customers find magnetic therapy can increase blood flow and speed up the healing of muscular injuries, and while there is no science-based evidence to support this suggestion, many people testify to the healing power of gold.
For artistic and fashion purposes, the gold lustre of the coating gives these disc magnets a stylish, less industrial appearance than the standard silvery coating and can provide a unique alternative to run-of-the-mill jewellery clasps and hooks. Thin gold surface coatings on permanent magnets also offer a degree of protection against corrosive atmospheres, such as salt air and humidity, which over time can have a detrimental effect on regular nickel-coated Neodymium products.
Although this deceptively petite magnet is only 4mm in diameter and 1mm thick, it has the power to hold weights over 150 grams, perfect for securing bracelets and necklaces without detracting from the overall beauty of the items themselves.
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.
