Neodymium Block Magnets
The unusual metric dimensions of this rare earth Block magnet exactly correspond to U.S. Imperial measurements of 2 x ¼ x 1/8 inches. Neodymium Block magnets are suited to applications that require strong magnetic hold or heavy duty magnetic power for commercial purposes.These requirements can also occur in the workplace, at the office or when taking on DIY projects at home. This wide,narrow, rectangular Block magnet has a broad and narrow pole area that can bond with ferrous surfaces very securely while taking up very little vertical space. This is often useful when a magnet needs to fit into narrow spaces or needs to be incorporated into products that have a low profile or slimline look with limited height space to offer. Different magnetic shapes have unique capabilities and are accordingly suited to widely differing applications. Although rare earth magnetic products attract premium pricing, many Frenergy customers find the benefits of permanent power, superior strength as well as the space and overall weight saving benefits, far outway the higher initial cost of Neodymium products. Other features such as their attractive silvery nickel-coated appearance that also improves the magnet’s overall durability make them even more appealing to customers looking for value.

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.
