Uses for our rare earth disc magnets:

Practical applications for the heavy-duty power of Neodymium magnets of all shapes, grades and sizes are almost limitless. Magnets offer self-generated and permanent power with the intrinsic ability to relocate themselves into the correct position. Their practical and efficient operation makes strong Neodymium magnets a widely appreciated alternative by consumers to more conventional methods of attachment and holding. Magnets revolutionise the design of everyday products and can modernise the designs of both artists and hobbyists. Although Neodymium magnets require a higher initial financial outlay their reliability and unrivaled magnetic strength make them more cost-effective over time. The rare earth minerals provide the strength of Neodymium that makes them popular with customers and these round-shaped magnets are one of the most commonly used magnets of all.

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.

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.

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.
