About Neodymium Iron Boron Magnets


    Collectively known as Neodymium Iron Boron magnets,it is alloy of the  Lanthanide 

group of  elements  that  Composed  by   neodymium,  iron,  boronand  a  few  transition

metals like Dysprosium,   Gallium .etc,  Through  these  melting ,pressing,  sintering,

machining, Coating, magnetizing processes,  to form those what we called  block,  bar,

Cubic, cylinder, ring,arc shapes.


   
  NdFeB magnets are available in sintered as well as bonded forms.  The bonded form

need almost no machining yet tolerance is small,  The flux of the bonded form  is up to 

10 MGOe  while sintered form available to reach 52 MGOe. The sintered form usually 

requires some finishing operations in order to suit mechanical tolerances.



  Plating NdFeB is a difficult process, coating,acidification,passivation each process 

should be acidity soft and temperature friendly . Zinc, Nickel, NiCuNi  and  Epoxy  

plating providegood corrosion resistance  and nice appearance for NdFeB magnets.
 
 
 
  All Sintered NdFeB magnets are anisotropic that can only be magnetized in the

orientation direction. Bonded magnet is isotropic and can be magnetized in any 

direction  magnetizing range is from 1koe-100koe which depend on magnets' 

size, grade and what the magnets for. 


 
   As the most advanced commercialized permanent magnet materials, NdFeB magnets 

are available in a number of different grades that span a wide range of properties and

application requirements.
