Neodymium Block magnets have permanent, powerful magnetic fields and include square and rectangular-shaped Neodymium magnets of varying sizes. The extensive Frenergy Neodymium Block magnet range is sure to have the right magnet for your application. Small rectangular Neodymium magnets have excellent holding strength and this thin rectangular item can be glued to an object or surface to make it compatible with steel or, when two magnets are used correctly, a neat and removable bond can be established between non-ferrous surfaces. This type of magnetic attachment is becoming increasingly popular with designers, artistic types and anyone who wants to give their product a unique and innovative edge. These thin rectangular magnets don’t require a lot of space to operate in and can often be used to replace the unsightly and less sophisticated traditional attachment systems such as screws, nails and bolts.

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.
