Special requirements of an application or the magnet material itself – NdFeB in non-corrosive design – can make it necessary to provide magnets with a coating. However, there is no universal coating, the respective coating must be adapted to the application.
Coating type | Thick (μm) | Color | WorkingTemp. (°C) | PCT (h) | SST (h) | Characteristics |
White Zn | 5-20 | Blue and White | ≤160 | – | ≥48 | Anodic coating, low cost |
Colored Zn | 5-20 | Iridescent | ≤160 | – | ≥72 | Anodic coating, low cost |
NiCuNi | 10-30 | Silver White | ≤390 | ≥96 | ≥48 | High temperature resistance |
PVD Al | 5-25 | Silver White | ≤390 | ≥96 | ≥96 | Excellent adhesive force, |
