Strong Neodymium Magnet Discs & Cylinders

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 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 industrial, technical, commercial and consumer applications.

Neodymium Disc Magnets in Premium Grades & Sizes

Magnet Shop offers a large inventory of licensed neodymium magnets available for online purchase at bulk discounted prices. From micro-sized disc magnets measuring 0.1” in diameter to large cylinder magnets that hold up to 68 lbs. Premium grades range from N30 to N52 which is the highest grade available in today’s market.

Neodymium Disc Magnet Features & Characteristics

Neodymium Magnets Approximate Pull Information

The approximate pull info listed is for reference only. These values are calculated under the assumption that 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 actual 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. top

Manufacturing Methods for Neodymium Magnets

Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings. top

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. top
