The most common permanent magnet materials are shown below. For more exotic materials and alloys, please contact us. Click on the links to view the variety of grades and specifications available within each type of material.

Neodymium (NdFeB)

Developed in 1982, Neo magnets are the strongest magnets available (in terms of energy product). Because of this, they are used in more products and industries than any other permanent magnet. While susceptible to degradation in water and with exposure to intense heat, these downsides can be mitigated through coating, encapsulation and the correct choice of coercivity. Contact us to determine the best grade for your application.

Samarium Cobalt (SmCo)

While not able to match Neo in magnetic field strength, SmCo addresses the downsides of Neo for many applications. SmCo is not subject to quick oxidation and can withstand extreme temperatures. For more volatile environments, SmCo is usually a good choice of material. Contact us to determine the best grade for your application.

Alnico (AlNiCo)

The oldest of the man-made permanent magnets, this material has a plethora of uses. While sacrificing the energy product of Neo and SmCo, Alnico is all but immune to oxidation and temperature - it can handle extreme environments and hold charge. Please keep in mind, certain grades can be detrimentally influenced by other magnetic fields. Contact us to determine the best grade for your application.

Ceramic (FeO)

Ceramic (Ferrite) magnets are chosen mainly for cost. Used in everything from motors to dipoles, whenever a large amount of material is needed Ceramics should be looked at as an option. Contact us to determine the best grade for your application.
