Neodymium Disc Magnets
Small Neodymium Disc-shaped magnets are easy to conceal yet also able to support much heavier weights than other magnetic materials. The invisible magnetic field also means it is difficult to detect the method of attachment when a Neodymium style magnet is used. When a strong bond for your artistic creation or important work project is required, Neodymium magnetic power can be used to create a sturdy bond without using unsightly and damaging fasteners like screws and rivets. The bond between a metal and a magnetic material is clean and simplistic. It is also easy to apply and quick to remove with the application of moderate physical force. This extremely strong Neodymium disc magnet can be glued to the base of any type of product, hobby or craftwork to give it stability on a metal surface or to enable it to attract to another magnet.

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.
