Quick Facts approximately Neodymium Magnets
Required saturation magnetization field: ≥ 33 kOe.
Manufacturing methods - sintering (maximum common), injection molding, laminating, or calendering.
Available shapes blocks, rods, discs, rings, arc segments, etc.
Available grades: Current the highest grade N58
Machining: Neodymium magnets should be grinded by diamond wheels. Compare to other magnetic material, such as AlNiCo, SmCo, NdFeB magnets are relativer easier to machine. With advanced technology, we can machining mirco with size 0.1mm and can processing the magnets with strange shape.

Surface treatment of NdFeB magnet material
Painting, coating or plating of NdFeB is usually recommended, although certain grades have recently been manufactured which exhibit higher oxidation resistance.
Plating NdFeB is a difficult process, and commercial plating companies unfamiliar with the specialized plating techniques required are unlikely to achieve plating with good adhesion on new magnets.
Nickel, zinc or tin plating provides good corrosion resistance for NdFeB magnets, but these may require longer lead times or larger volumes. New magnets can also be plated using ion vacuum deposition (IVD) technology. The thickness of this special plating is very controllable and provides excellent adhesion to the material.
NdFeB has also successfully developed a variety of organic coatings that exhibit good corrosion resistance. For particularly harsh environments, it is recommended to use a combination of coating techniques or to encapsulate the material in a hermetically sealed housing.
