NdFeB Magnet is being used to produce high performance motors, relays, holding systems, magnetic bearings, magnetic couplings, magnetic switches, etc.
Rare Earth are the Neodymium (Nd) Iron (Fe) Boron (B) types and Samarium (Sm) Cobalt (Co) classes. The most commonly produced material is neodymium iron boron (NdFeB). This group of magnetic materials provides the highest available magnetic energies of any material. NdFeB magnets allow small shapes and sizes with high magnetic fields. Energy products range from 26 MGOe to about 45 MGOe.
Sintered NdFeB magnets - will produce the highest magnetic properties. NdFeB is sensitive to heat and should not be used in the environments that exceed 180 °C. and both NdFeB and SmCo are available in sintered as well as bonded forms.
Facts:
- Allows small shapes and sizes with high magnetic field
- Sensitive to heat
- Some finishing operations required in order prevent corrosion
