Neodymium Disc Magnet
Frenergy products include a very wide range of small, extremely strong Neodymium disc magnets with varying diameters and height dimensions. These dimensions, combined with the particular “N” Grade of the rare earth material inside the silver coating of each particular magnet, determines the level of holding strength and magnetic energy each magnet can produce. Higher grade magnets have more strength and holding ability. Choosing a magnet that is suitable for your needs may require all these variations to be taken into account so the correct magnet size or correct holding strength for your application is identified. Small, super strong disc magnets are easily incorporated into delicate craft and hobby-type creations where weight limitations and space restrictions need careful consideration. Many customers use these super strong rare earth disc magnets to simply hold, clamp or bond materials together or to make them compatible with ferrous metal. Strong neodymium discs are also used to generate the permanent magnetic power required to operate highly complex industrial warning systems, consumer electronics, audio equipment and many other modern-day devices.

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.
