Bonded Neodymium magnets are composed of Neodymium, Iron, Boron and binder. Bonded Neodymium magnets are manufactured by compression molding or injection molding. Compression bonded Neodymium magnets have higher energy products and simpler shapes than injection bonded Neodymium magnets. There are both isotropic and anisotropic bonded Neodymium magnets.
