Product Description
Brand by Lord said of sintered ndfeb permanent magnet materials and magnetic properties of 2 kinds of three parts, the first part is given priority to, according to the chemical symbol ND of neodymium, iron chemical symbol of FE and boron element, chemical symbol B, the second part is the line in front of the Numbers, is the material nominal value of the maximum magnetic energy product (BH) Max (in kj/m3), the third part to slash the number, the intensity of magnetic polarization coercive force value (unit for KA/m), one over ten of numerical adopts the nearest integer.
Example of grade: NDFEB380/800 means that (BH) Max is 366-398kj /m3, and Hcj is 800KA/MR sintered NdFeb permanent magnet.
Sintered NdFeb permanent magnetic material has excellent magnetic properties, widely used in electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, the more common are permanent magnet motor, speaker, magnetic separator, computer disk drive, magnetic resonance imaging equipment and instruments.
Technological process: batching → melting ingot/strip spinning → powder making → press → sintering tempering → magnetic testing → grinding → pin cutting → electroplating → finished product.
Among them, batching is the basis and sintering tempering is the key.
