Neodymium Iron Boron (NdFeB)
Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, and a few transition metals. Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron. We develop these rare earth magnets that are extremely strong for their small size, metallic in appearance and available in simple shapes as rings, blocks and discs.
Manufacturing Rare Earth Magnets
Usually the elements are melted together and milled into a power that is dry-pressed to shape in the presence of a magnetic filed. The materials are then sintered, aged, ground to dimension, magnetism and tested and tested. They are called “rare earth” magnets because the elements of neodymium and samarium are classified as such in the lanthanides section of the periodic table of the elements.
