NdFeB Neodymium Permanent Magnets

NdFeB Neodymium Permanent Magnets
Product Details

The neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure.

Key Benefits of Neodymium Magnet Material

Very high strength.

Relatively low cost: by weight, about 20x Ferrite magnets, by "Dollar per BHmax" about 1.5x ferrite magnets. 

Relatively easy to machine, compared to alnico and samarium cobalt magnets.

Key Challenges of Neodymium Magnet Material

Properties deteriorate rapidly at temperatures in excess of about 150°C depending on grade and permeance coefficient at which the magnet operates at.

Most grades of NdFeB magnets need to be protected against oxidation by coating or plating the magnets.


  • NdFeB powder is very fine and when dry can ignite spontaneously; special care must be taken when handling NdFeB powder. 

  • NdFeB magnets are very powerful; special care must be taken in handling these magnets to avoid injuries. 

  • NdFeB magnets are susceptible to corrosion.
