Magnetic Disc 20mm x 5mm Product Description:
Neodymium Rare Earth magnetic material is the strongest magnet sold today. This Rare Earth Disc has a magnetic flux reading of 2817 Gauss and a pull force of 7 kg. It has a diameter of 20mm and a height of 5mm. This magnet is protected by a nickel coating, providing resistance to wear and tear.
Uses for our Neodymium Rare Earth Disc Magnets:
These strong magnetic discs are used in many industries and settings. They can be used in the home, for industrial purposes, craft purposes and more. This 20mm x 5mm disc is commonly used in specialist engineering applications for its strong pull strength and compact size.
Neodymium disc magnets are commonly used in the design and build of components in the aviation industry. Magnets have achieved a trusted and established reputation in traditional manufacturing techniques. In complex aviation systems, engineers often choose these effective disc magnets for the job.

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.
