Neodymium Ring Magnets
Neodymium magnetic products are the unbeatable leader when it comes to holding strength either at home or in more industrial settings. Strong rare earth ring shaped magnets have similar benefits to those of slim, low height disc magnets but have the additional convenience of a central hole by which the magnet can be attached to another surface with wire or string. This can be done either casually or for the long term and by using this simple and flexible form of attachment, commitment to invasive and permanent surface-damaging types of fasteners is no longer necessary. This low-tech but efficient form of attachment also allows the strong, circular ring-shaped magnets to be quickly relocated or removed completely for use at a later date. Magnetic hold can be used to display artwork, support decorations, hang signage or to keep doors and cabinetry closed. Ring-shaped Neodymium magnets are popular with many customers who find them easy to use and adaptable to a wide range of holding requirements around the home or workplace.

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.
