烧结钕铁硼
钕铁硼磁铁又称钕磁铁,磁性能非常强大。钕磁铁是稀土永磁铁的一种,属于硬磁,另一种常见的稀土磁铁是钐钴磁铁。
与其他永磁材料相比,烧结钕磁铁在磁性能上优势突出。它具有极高的磁能积、矫顽力和剩磁,同时它的机械性优异,易于加工。这些优异的性能使烧结钕铁硼永磁体广泛应用于现代工业和电子技术中。它常见的应用有永磁电机、扬声器、磁选机、计算机磁盘驱动器和磁共振成像设备等。 2000年,稀土永磁总产值首次超过铁氧体。 2010年,烧结钕铁硼永磁产值超过铁氧体,成为永磁行业名副其实的“主角”。

烧结钕铁硼磁铁因其强大的磁性推动了工业的发展。在所有磁铁中,它单位体积能提供的磁力最强,这意味着它使设备或产品更小。例如,在过去,在没有永磁铁之前,电机通线圈提供的磁力来驱动。当电流通过电线时,电线线圈会产生磁场。于是磁性能要求越高,线圈就越大,电机就大。现在直流或无刷电机需要一个小的钕磁铁来驱动电机。现在越来越多的产品用到烧结钕磁铁,比如永磁电机、扬声器、磁选机、电脑磁盘驱动器、磁共振成像设备、仪表等。
电动汽车产业的发展正在推动烧结钕磁铁市场的快速延伸。驱动电机、发电机、电控系统,这些领域少不了钕铁硼磁铁。
