Materials Sintered Neodymium-Iron-Boron
Neodymium magnets, Sintered NdFeB(Neodymium-Iron-Boron) rare earth magnets are the strongest magnets in the world up to date, with high flux density and high coercivity, the range of energy product is 26--54MGOe. Sintered NdFeB magnets are anisotropic and only magnetized in one direction.
Coatings of NdFeB block magnet self-adhesive: Passivation, Nickel, Zinc, Tin, Aurum, Copper, Epoxy, Chemical, etc.
Surface | Coating | Thickness (Microns) | Color | Resistance |
Passivation | | 1 | Silver grey | Temporary protection |
Nickel | Ni+Ni | 10-20 | Silver bright | Excellent to humidity |
Ni+Cu+Ni |
Zinc | Zn | 8-20 | Shining light blue | Good to salt spray |
Cu-Zn | Shining color | Excellent to salt spray |
Tin | Ni+Cu+Sn | 15-20 | Silver | Superior to humidity |
Aurum | Ni+Cu+Au | 10-20 | Shining gold | Superior to humidity |
Copper | Ni+Cu | 10-20 | Shining gold color | Temporary treatment |
