       Neodymium Magnets, also known as NdFeB, NIB, or Neo magnets, are the most widely-used type of rare earth magnets. It is the strongest type of permanent magnet made from an alloy of Neodymium, Iron, and Boron with the Nd2Fe14B tetragonal crystalline structure. 

            It is important to know that a neodymium magnet ring is very hard and brittle and can break if they are dropped. Neodymium magnets can be assembled into products that use strong adhesives, but contact surfaces should all be clean and dry before bonding.
        It has replaced other types of magnets in many applications in modern products that require strong permanent magnets.

 Neodymium Ring magnets are often used in:      

  • High performance motors  
  • motors in cordless tools
  • hard disk drives
  • magnetic fasteners
  • Magnetic couplings
  • Magnetic separators
  • Electronic Solenoids
