When so many products are mass produced, designing equipment and products tailor-made to your needs can be difficult without the right tools. Rare Earth Neodymium magnets offer a solution in the design of lockers, cabinets, shelving, pallet racks and loading dock equipment, as well as in home decor, fashion, craft - anywhere a strong, secure hold is required, without the appearance of a bulky magnet.
The beauty of using these powerful disc magnets is in the flexibility they allow in specific product or service design, as well as their durability and strength.
Rare Earth Neodymium magnets offer options unmatched by ferrite type magnets or other magnetic materials. The predictability and reliability of Neodymium magnets, as well as their cost effectiveness means they are an important part in any design or construction where controlling production costs is vital and performance is key.
This Disc has a diameter of 5mm and a height of 4mm. It has a magnetic flux reading of 5342 Gauss and a pull force of 539 grams.
This permanent magnet has a nickel coating for corrosion resistance and for the prevention of chips.

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.
