Block NdFeB Magnet
Neodymium block magnets (ND-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and disc
1. Attributes of Neodymium
2. Very high resistance to demagnetization
3. High energy for size
4. Good in ambient temperature
5. Moderately priced
6. Material is corrosive and should be coated for long term maximum energy output
7. Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.
Magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors (automotive starters), computer rigid disc drives, printers and speakers...
