Rare Earth Magnets

Rare Earth Magnets

Rare earth magnets are the most powerful magnetic material available.  The two types of rare earth magnets are Neodymium and Samarium Cobalt - and we have hundreds of sizes in stock. Their sizes range from the size of a pinhead to a block the size of your hand.  They're typically used where high performance is required.

More About Rare Earth Super Magnets

Rare earth super magnets are the strongest type of permanent magnets. When compared to common ferrite and alnico magnets, the strength they posses is significant.

Ceramic magnets have a magnetic field of only 5- to 100 milliteslas, while rare earth permanent magnets are powerful enough to create a magnetic field of more than 1200 milliteslas.

Rare earth super magnets are favored for certain applications because of this strength, and their ability to perform in extreme conditions. Common applications of rare earth permanent magnets are in computer hard drives, audio speakers, fishing reel brakes and bike dynamos.

There are two types of rare earth varieties- neodymium or a combination of cobalt and samarium.

Neodymium Magnets

Neodymium products are the stronger of the two. In general, they also feature a lower price than samarium.

It is a high energy magnet that is offered in grades exceeding 50 MGOe, and it is most popular for electromechanical applications because of this strength and affordability. Its one drawback is resistance to corrosion and extreme temperatures- maximum service temperature for this material is typically 125° – 150° C. Products are usually coated with gold, nickel, zinc or tin to improve corrosion resistance, but for high heat applications, Samarium is a stronger choice.

Samarium Magnets

Samarium Cobalt magnets are less common than Neodymium magnets because of their weaker magnetic field, and higher cost, but for high temperature applications, they are the best choice. Their high Curie point- the temperature at which magnetic moments change direction- allows Samarium Cobalt magnets are able to perform in extreme temperature environments.

These types of products maximum grade is 26 MGOe. You can purchase them in small & large blocks, discs, and rings.
