Neodymium (NdFeB) Magnets

Temperature Considerations with Neodymium Magnets

A low coercivity grade Neodymium magnet may begin to lose strength if heated above 176°F (80°C). High coercivity grade Neodymium Magnet shave been developed to function at temperatures up to 428°F (220°C) with little irreversible loss. The need for low temperature coefficient in neodymium magnet applications has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade.

Features include

• Neodymium magnets are the most powerful commercially produced magnets.
• Neodymium  magnets are magnetized through the thickness.
  
• Uncoated NdFeB magnets may corrode in humid conditions.
• Operating temperatures vary among material grades. For a comparison of neodymium material grades, please see our chart of material properties.
• Neodymium magnets are often assembled into products using strong adhesives such as Loctite 325. Make sure that all contact surfaces are clean and dry prior to bonding. You may also be interested in our neodymium magnets with adhesive.
• Please use caution when handling magnetized neodymium magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.
