Product Description

Neodymium Iron Boron (NdFeB) or Neodymium magnets are extremely strong for their size. Available in various shapes including rings, blocks, discs, and custom configurations.

To prevent oxidation, these magnets are typically finished with protective zinc, nickel, or epoxy coatings.

Manufacturing process involves melting the elements together, milling into powder, dry-pressing in a magnetic field, sintering, grinding to dimension, magnetizing, and testing. Classified as "rare earth" magnets due to their neodymium content from the lanthanides group in the Periodic Table.
