An overview of the each kind of product is divided into several brands according to the maximum magnetic energy product size
The grades of NdFeb magnetic materials are: N35 -- N52,35M -- 50M, 30H -- 48H,30SH -- 45SH, 28UH -- 35UH,28EH -- 35EH.
Example of grade: 048021 means that (BH) Max is 366-398kj /m3 and Hcj is 800KA/m of sintered NdFeb permanent magnet.
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.
Ndfeb surface treatment:
2. Inactivation of inorganic salts;
5. Vacuum deposition
