Sintered NdFeB magnet
The most powerful rare earth magnets available, sintered NdFeB is produced by powder metallurgical process with chemical composition of Nd2Fe14B, which are hard, brittle and easily corrode, involving the sintering of compacts under vacuum. Poorest corrosion resistance of all commercial magnetic material. Grinding and slicing possible; very reactive with moisture and oxygen; coating may be applied depending on the expected environment. The sintered NdFeB magnet has high remanence, high coercive force, high-energy product and high ratio between performance value and product cost. It may be easily formed into various sizes. The intrinsic coercive force is over 30,000 Oe. Neodymium iron boron magnets lose -0.09 ~ -0.13% of Br/°C. Their working stability is under 80°C for low Hci. Neodymium magnets and above 200°C for high Hci Neodymium iron boron.
