Neodymium Magnets

The Most Powerful Magnets Available Today!

Neodymium (or “Neo”) magnets are a type of Rare Earth Magnet, with the highest magnetic properties, and the most powerful commercial magnets available today. Neo magnets are used in a wide range of technical applications, from wind generators to atom smashers. While extremely powerful, today Neo magnets have become more affordable for many non-technical applications such as holding, magnetic jewelry clasps, toys, filters and separators, name tags, and a host of others! See below for more detailed information about this material-


Neodymium Quick Tips

  • Characteristics: Neodymium magnets are far less subject to cracking & chipping and less costly than the other Rare Earth type of magnetic material, Samarium Cobalt ("SmCo"). Neo is more sensitive to temperature - where this is critical, SmCo may be the better choice, since its magnetic properties are very stable at elevated temperatures,  Although Neo magnets are more costly than ceramic magnets, they pack a much stronger punch! With Neo magnets, you can use a smaller magnet to achieve the same objective – potentially leading to a lower overall cost as the size of the entire device can shrink.
  • Grades & Shapes: Grades 30-52 are available in disc, rectangle, square and rod shapes, and can be custom manufactured to meet your specialty requirements.  Just let us know what you are looking for by clicking on the Special Request  icon at the top of the site.  

  • Applications: Neodymium Magnets are used in many industries for applications such as audio equipment (microphones, headphones, and loudspeakers) hard disk drives, pumps, bearings, MRI scanners, electric vehicles, wind generators, high performance motors, actuators, magnetic therapy, anti-lock braking systems, levitation devices, door latches, model making, arts & crafts, home improvement (DIY-fixing furniture, hanging pictures etc.) POP displays & more.

  • Temperature: Neo magnets should not be used in temperatures above 130° C (240° F) without careful magnetic circuit design - please discuss your application with our engineers if you plan on using these magnets above this temperature.

  • Bonding: Neo magnets are often assembled into products using “super glues” such as Loctite 325- as with all bonding applications, always ensure that bonding surfaces are clean and dry prior to bonding for best results.
  • Coating: Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions. 

  • Safety Precautions: Neo magnets are hard and fairly brittle, and have a very high magnetic strength – they can snap together with great force - please ensure that all personnel handling these magnets are aware to handle them carefully to avoid injury. They can chip or break if dropped or if snapped together - so take special care when handling these powerful magnets!
