Rare Earth (Neodymium) Disc Magnets

Disc magnets come in a wide variety of diameters and thicknesses. The strength of the magnet is informed by the amount of magnetic material present. Disc magnets are defined as round magnets with a diameter that is greater than the thickness. This characteristic means Neodymium Disc Magnets provide a strong magnetic field and high coercivity.

Just like the full Neodymium range, disc magnets come in a variety of coatings with Nickel being the most common. When choosing the right magnet for you it is worth considering which coating might serve to best support your project. Coatings such as Gold or Teflon are better suited to corrosive elements such as saltwater or humidity. However plastic, Zinc, and Epoxy fare better for applications that require glue. For a full breakdown of the benefits of our coating options please refer to our Knowledge Base.

Like all Rare Earth Magnets, Neodymium discs are not ideal for high-temperature applications as they do not have resistance to temperatures over 80 degrees Celsius, as they will begin to lose their magnetism and become permanently damaged. Alnico, Ferrite, and Samarium Cobalt are all viable alternatives for high-temperature utilisation.

Neodymium Rare Earth Magnets Uses

Rare Earth disc magnets combine the power of Neodymium in the compact form of a disc shape. Fantastic value for money means that Neodymium discs are among the most commonly used magnets in our range. This round shape of Neodymium Magnet is frequently used as a component part of machinery as the magnetic field of a round magnet can be calculated and targeted more exactly than rectangular magnets.

Neodymium disc magnets are also popular as a closure system for brochures, binders, packaging, and bookbinding. Their slim profile makes them ideal for this type of application as they can be easily embedded into relatively thin cardboard, plastic, and wood to create a streamlined finish.

Likewise, Point of Sale or POS displays commonly utilize disc magnets as a means of attaching to product display racks or metal poles. The signage can then be easily removed and updated when required. The flat aspect of the disc shape enables it to withstand forces like the occasional bump of a passing customer making them ideal for this application.

Certainly, we can not forget craftspeople as one of the biggest advocates of the merits of Neodymium disc magnets. The huge range of sizes starting from the very petite such as a 2mm diameter disc, means they can be incorporated into all sorts of hand-crafted items. The minimal profile of a disc magnet enables it to be easily hidden from the casual viewer and does not distract from the artistic creation, whether it be paper, wood, or even glass.
