SmCo magnets have excellent magnetic properties, with a maximum energy product of up to 32 MGOe, a low temperature coefficient and high stability. Samarium Cobalt (SmCo) magnets contain less free iron than Neodymium magnets and therefore provide better corrosion resistance than Neodymium magnets. NdFeB magnets can be coated with electroplate, epoxy and other coatings that can give them excellent corrosion resistance even very challenging environments. They are called are rare earths, because Samarium and Neodymium are both found in the Lanthanide series of metals on the Periodic Table, so the properties and crystal structures of these magnets are very similar to each other. They are both very strong magnets with very high BH Max (Maximum Energy Product) and high Coercivity (resistance to demagnetization) and they are both commercially important on a large and growing scale. NdFeB typically has about 1.5% cobalt added to improve corrosion resistance a little bit, but that is a very small percentage of cobalt compared to what’s in SmCo magnets. Our data sheet on Surface Treatments can be found here. Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets.
