Rare earth magnets are very strong magnets made from alloys of rare earth elements. They are the strongest among the permanent magnets made. These magnets can be manufactured through sintering, compression bonding, injection molding and extrusion.

Since their prices became competitive in the 1990s, rare earth magnets have been replacing Alnico and ferrite magnets in many applications in modern technology requiring powerful magnets. Their greater strength allows smaller and lighter magnets to be used for given applications that require the high strength. The material is easily magnetized in one direction, but is able to prevent magnetic pull in any other direction.

There are two types of rare earth magnets, Neodymium and Samarium-Cobalt. Their shapes can include arc, block, cube, cylinder, disc, rod, sphere and many more. You can browse through our current shapes and sizes to find the right magnet for your application. If you need a custom design, we can work with you to create unique specifications for all shapes and sizes. Contact Magnetic Hold to find out how we can help provide you rare earth magnets.

Caution!

Extreme caution must be taken when working with rare earth magnets. Magnets larger than a few centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a metal surface, even causing broken bones. Magnets allowed to get too close to each other can strike one another with force to chip and shatter the brittle material, and the flying chips can cause injuries.
