NdFeB magnet

NdFeB Magnet: The full name of NdFeB magnet is Neodymium Iron Boron magnet. It is the third generation of rare earth magnet and has been commercially available since the mid -1980's. It is the most powerful rare earth magnet today possessing high energy product from 8MGOe to 52MGOe and Neodymium Iron Boron has good resistance to external demagnetization fields because of its high Intrinsic Coercive Force (Hci). This resistance makes Neodymium magnets an excellent choice for electromechanical applications. With abundant raw material, NdFeB cost less. Also the density of NdFeB products is about 13% smaller than SmCo products, because NdFeB magnets are more prone to oxidation than any other magnet alloy, so for most applications, coating or plating the magnets is recommended.
