MPCO Rare Earth Magnets

The term rare earth magnet is a general term that refers to magnets that are made from alloys of rare earth elements, typically either neodymium iron boron or samarium cobalt. Both of these rare earth alloys are manufactured by a powdered metal process, but the resulting magnets have several distinct differences.

Rare Earth Neodymium Magnets

Neodymium is the strongest available rare earth magnet alloy at up to 52MGOe.

Rare Earth Samarium Cobalt Magnets

Samarium Cobalt rare earth magnets are often used in high temperature applications.

Some of the differences between neodymium rare earth magnets and samarium cobalt rare earth magnets include:

Neodymium iron boron rare earth magnet are highly reactive to environmental conditions, whereas samarium cobalt rare earth magnets are very corrosion resistant.
Samarium cobalt rare earth magnet will withstand high temperatures without demagnetizing, while care must be used when utilizing neodymium above ambient room temperatures.
Neodymium iron boron rare earth magnets are moderately priced and offer a good value when compared to performance. Samarium cobalt magnets are considerably more expensive due to their cobalt content.
Neodymium iron boron rare earth magnet are less brittle than samarium cobalt rare earth magnet and are easier to machine and integrate into magnetic assemblies. Both alloys require diamond tooling, EDM, or abrasive grinding when machining.
