Sintered Magnet​

 

Sintered neodymium magnets are mainly composed of an alloy of neodymium, iron and boron, forming a tetragonal Nd2Fe14B crystal structure. Neodymium magnets have the strongest magnetic properties on the market today. During compaction, magnetism changes with orientation, size, and shape. They are available in a variety of shapes, sizes and qualities. The new magnets can be used in a variety of applications, including high-power motors, brushless DC motors, magnetic separation, MRI, sensors, switches, and speakers.

The main advantages of neodymium magnet material

 

  • Very high strength.
  • Relatively low cost: about 20 times more than ferrite magnets by weight, and about 1.5 times more than ferrite magnets on a per BHmax basis.
  • Relatively easy to process compared to Alnico and SmCo magnets.

 

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.
