Neodymium Disc Magnets
Once a few small, round rare earth discs have been glued onto a surface or material, that material or product can be suspended from ferrous surfaces permanently or on a convenient as-needed basis. Many applications for magnetic attachment occur in factories, industrial landscapes, agricultural settings, mine sites and in environments where motor vehicles, trucks or machinery are regularly in use. Warning signs, lighting, electrical cabling and small hand tools are also able to be suspended magnetically with small round magnets like this N35 Grade Neodymium disc. Screws and other more conventional penetrating fasteners reduce the structural integrity of the steel surfaces they bind to which can lead to water and dust ingress and can cause costly corrosion issues over time. Magnetic attachment is a user-friendly and completely non-invasive form of attachment that can be used in commercial environments or at home. The permanent and consistent power of rare earth Disc magnets has led them to be a common component in audio equipment, electric motors and telecommunications tools including the ever-present smartphone.

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.
