Sintered NdFeB Magnet is one of the high performance rare earth permanent magnets, which use neodymium (ND), iron (Fe), and boron (B) as their main ingredients and is susceptible to demagnetization when exposed to elevated temperatures. There are many grades which can withstand high temperatures, but several factors will dictate the performance of the Neodymium magnet. There are also Sintered NdFeB, Sintered AlNiCo, Sintered SmCo and Sintered Ferrite.

Application for NdFeB magnet: 
Magnetic separator, Sensors, Wind generators, Vibration motors, DC motors, Servo motors, Linear motors, VCM, MRI, Loudspeakers, Linear actuators, drives, toys, bags, household appliances, microphone parts, transmission equipments...
