You can barely notice them and most of us wouldn’t know they’re even there, but tiny Rare Earth Neodymium magnets are doing some heavy lifting in an astounding range of applications. Strong Neodymium disc magnets create extremely powerful bonds, despite being a fraction of the size of magnets made from other magnetic materials. It’s this super-strength that has made Neodymium hugely influential in the design and production of a vast array of new products across various industries and pastimes. These tiny Rare Earth discs, weighing less than one gram each, with strong N50 Grade Neodymium inside, are hardly noticeable when used to bond two materials together. Even better, their sleek nickel finish can give a unique and modern feel to product design.
They are also easy to apply, because the small circular Neodymium magnets can be glued into position with epoxy glue or even sewn inside lightweight materials and garments to create stylish new closure and attachment options. For their size, Neodymium mini magnets generate immense holding power, so when it comes to attachment and holding challenges - problem solved.

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.
