Characteristics and Properties
Neodymium, also known as the "King of Magnets," is a type of rare-earth magnet, a blend of neodymium (Nd), iron (Fe), and boron (B). Its exceptional features, including high coercivity, high remanence, and high saturation induction, make it an excellent choice for numerous applications.
Comparative properties of Neodymium (NdFeB) and other magnet types:
| Neodymium (NdFeB) | Ferrite | Samarium-Cobalt (SmCo) | Alnico | |
|---|---|---|---|---|
| Coercivity | High | Medium | High | Medium |
| Remanence | High | Low | High | High |
| Saturation Induction | High | Low | High | Low |
| Temperature Range (°C) | -80 to 180 | -10 to 120 | -20 to 160 | -20 to 180 |
