Neodymium Disc Magnets

Click image to enlarge

Neodymium (also known as "NdFeb", "NIB" or "Neo") disc magnets are the most powerful rare-earth magnets available today. Available in disc and cylinder shapes, Neodymium magnets have magnetic properties that far exceed all other permanent permanent magnet materials. They are high in magnetic strength, moderately priced and able to perform well in ambient temperatures. As a result, they are the most widely-used rare-earth magnets for countless industrial, technical, commercial and consumer applications.

Strong Neodymium Disc Magnets in Premium Grades & Sizes

At Magnet Shop, our extensive inventory of licensed neodymium magnets is available for online purchase at bulk discounted prices. Premium NdFeB grades range from N30 to N52, which is the highest grade available in today's market. From micro-sized disc magnets measuring 0.1" in diameter to large cylinder magnets that hold up to 68 lbs, we have a vast selection of neo disc magnets to choose from for virtually any application.

Neodymium Disc Magnet Features & Characteristics

Neodymium Magnets Approximate Pull Information

*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Neodymium Disc Magnet Manufacturing Methods & Finishes

Our neodymium discs are sintered for optimal magnetic strength. Unless otherwise specified, these disc magnets are magnetized axially (the magnetic field runs through the thickness of the magnet, with each pole located on the flat surfaces of the disc). Available as either uncoated, or with finishing options including nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings for maximum protection against corrosion & oxidation.

Standard Dimensional Tolerances for NdFeB Disc Magnets

Standard diameter tolerances for Rare Earth Magnets (SmCo & NdFeB) based on the following dimensions:

  • +/- 0.004" on dimensions ranging from 0.040" to 1.000".
  • +/- 0.008" on dimensions ranging from 1.001" to 2.000".
  • +/- 0.012" on dimensions ranging from 2.001" to 3.000".

*Tolerance on thickness is +/-0.004” regardless of size.
