Neodymium Disc Magnet
This Neodymium Disc shaped magnet contains N50 Grade magnetic material which is one of the strongest grades available. Stronger than average grade magnets are suited to applications where space constraints create problems and make the use of a larger more powerful magnet impractical. Several disc magnets arranged with alternating poles within an assembly can make a powerful magnetic tool for holding or suspending heavy items from steel surfaces. Small disc magnets are often used inside plastic whiteboard markers and other low-tech applications where their high strength and light weight is an advantage. Since the 1980’s Neodymium discs have been instrumental in the development of sophisticated, high-tech Audio and Telephony equipment where their space-saving proportions, strength, sensitivity and accuracy enables them to convert sound vibrations into amplified electrical signals that can be transmitted or recorded for playback. Microphones and Loudspeakers use Neodymium magnet technology to produce high-fidelity, electrically amplified sound in a similar but converse operation to each other.
Disc shaped magnets attached to a surface with glue can also be very practical and versatile inclusions in handicraft projects, modelling, art and commercial advertising displays, exhibitions, outdoor markets and anywhere traditional fastening methods are inconvenient or unsuitable.
Frenergy has a comprehensive range of powerful Neodymium disc magnets in various diameters, pole orientations and grades that are able to suit nearly every application.

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.
