Sintered NdFeB magnets are a kind of rare RD magnets. Compared with conventional magnets e.g.: AlNiCo or hard ferrites, offer NdFeB magnets the tenfold power density. The excellent magnetic characteristics of sintered NdFeB magnets are based on the strong magnetic matrix phase Nd2Fe14B (tetragonal structure), with a very high saturation magnetization Bs (Bs = 1.6 T) and a high magnetic anisotropischen field strength Hcj of up to 41 kOe. The current energy product from NdFeB magnets amounts to up to 47 MGOe. In the laboratory an energy product was already reached by 55,8 MGoe. This achievement opened a far field of new application possibilities for the material.
Most frequent applications of sintered NdFeB magnets are:
Electroacoustics: Loudspeaker, headphone, microphones
Engines & generators: Stepping motors, servo actuators & DC machines
Hard Disk Drive assemblies
Sensor technology, measuring technique
We have developed new magnet for high temperature application !
Neodymium magnet is with much higher Br than any other magnets such as AlNiCo, Sm-Co etc, but it also has a disadvantage, that its maximum working temperature and temperature stability are much worse than other magnetic materials, which directly restrict the wide application of Neodymium magnet in some special fields. cylindrical ndfeb magnet
Usually, the temperature coefficient βHcj of Neodymium magnet is over -0.7%/℃, now we can supply new magnet less than -0.4%℃, this helps neodymium magnet with excellent temperature stability. Reversible temperature coefficient of Remanence( αBr) and Reversible temperature coefficient of Hcj is relative to ratio of length, square, length/thickness diagram( BH CURVE) etc.
If you need high temperature magnet for some special applications, we are ready to support you, also will be your best choice.
