neodymium permanent magnet

Having a combination of very high remanence and coercivity and as NdFe14B is their main element, our NdFeB magnets are the most powerful permanent magnets in the world at present, possessing the maximum energy product ranging from 26 MGOe to 52 MGOe. Having the excellent magnetic characteristics, abundant raw material and relatively low prices, NdFeB offer more flexibility in new designations and replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices. Neodymium magnets are all graded by the material they are made of. As a very general rule, they are divided into a group of grades according to the coercivity of the magnets, the higher the grade, the stronger property the magnet has, such as: from N- M - H - SH - UH – EH - AH. Apart from that, their maximum BH is more than ten times that of Ferrite, and bearing strong and stable properties, they can work well at temperature up to 240 degrees C.
