Neodymium Disc Magnet
The extremely thin height dimension of less than 1mm of this super strong N52 Grade Neodymium disc makes it suitable for highly specialised applications where very small spaces and little impact damage to the magnet is likely. This environment is usually found in electrical products like the microphones and loudspeakers that are used by the sound recording and communications industries. Inside these products thin, sensitive magnets translate sound waves via the magnetic field into electrical signals for sound amplification and improved clarity. Less technical uses are also possible for these fragile high-grade Neodymium discs but careful placement to protect the brittle magnet from damage is essential. Homemade jewellery and fashion items can use these small Neodymium disc magnets to create clasps, closures and pin-free attachment points for a variety of fashion accessories.

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.
