Neodymium Iron Boron Coating Options
Magnets may need to be coated, depending on the application for which they are intended. Neodymium Iron Boron magnets are particularly susceptible to corrosion and are often protected in this way.
Refer to the table below for coating options for fully sintered Neodymium Iron Boron permanent magnets.
| Coating Type | Thickness | Appearance | Salt Fog Duration | Temperature |
| Ni-Cu-Ni | > 20μm | Metallic | > 120 hours | < 200°C |
| Zinc | > 20μm | Metallic | > 48 hours | < 200°C |
| Aluminum IVD | > 10μm | White | > 24 hours | < 500°C |
| Electroless Ni | > 20μm | Metallic | > 24 hours | < 200°C |
