What are the appearance defects of NdFeB magnetic materials?
The appearance defects of NdFeB magnets are mainly produced in the production process. The common appearance defects are magnet cracks, cracks, pits, angle drops, blisters, knife marks, sand holes, pockmarks, etc. In addition, it is possible that the electroplating layer on the magnet surface is wrong, because most of the electroplating of the magnet manufacturers are sent out, which may be wrong. When QC checks the incoming goods, they can see whether they are consistent with the requirements of their own company.
