Rings
Plastic bonded magnets are magnets on bases of Neodymium-Iron-Boron (NdFeB). These magnets are produced by the dry pressing method. All products manufactured this way must have surface treating because tey tend to corrode. NdFeB based magnets generally have higher magnetic properties than typical ferrite magnets.
Application
- Electrotechnics: magnets into the speakers, controller systems etc.
