烧结钕铁硼永磁体是以金属氧化合物nd2fe14b为基础的稀土永磁材料。相对于al-ni-co系永磁和铁氧体永磁材料，钕铁硼具有极高的磁能积和娇顽力，理论上可等于自身重量的640倍重物。高能量密度的优点使钕铁硼永磁材料在现代工业和电子技术中获得了广泛应用。如：电动机、风力发电、电动自行车电机、核磁共振、磁选机、除铁器、防泄漏阀门（气、水、油）、仪器仪表、医疗保健器械、音响设备（如喇叭、蜂鸣器）、手机、汽车、电子、通讯设备、计算机、玩具、包装（如礼品盒、箱包）、衣服扣等行业和领域。

ndfeb is a permanent magneticmaterial with the metallic composition of nd2fe14b. compared withthe casing of permanent magnetic material al-ni-co and permanentmagnetic ferrite, ndfeb has stronger coactivity and (bh)max; whichcan attract heavy objects weighing over six hundred and fortypounds times its weight. its merit of higher energy density resultsin its wide use in modern industry and electronic technology suchas: loudspeakers, high performance steppers, dc′s, servos, linear motors, generators, magneticresonance′s, magnetic separations, iron removers, magneticsuspension, computer＆car parts, communication e, machinemeters, wax＆leakage resistance (gas, water, oil andothers).
