Among commercial magnet materials, the rare earth Neodymium Iron Boron(NdFeB) and Samarium Cobalt(SmCo) magnets are the most powerful in the marketplace. These Rare Earth materials possess the hightst Br, relatively high Hc and high BHmax. In many cases, NdFeB is a more economical alternative to SmCo, but it’s only suitable for certain applications due to its temperature sensitivity and susceptibility to oxidation.Rare Earth magnets have an approximate energy product range of 10~53 MGOe. Before choosing a Neo magnet be sure to consider your application’s maximum operating temperature. Let our knowledgeable engineering department assist you in determining the best grade and size of Neo magnet for your application.
