Neodymium Magnets NdFeB (neodymium Iron Boron) magnet is the third generation of rare-earth permanent magnet, named “king magnet” for its great performance and competitive price.

It is widely used in modern industry and electronic technology.

Neodymium Magnets are far more stronger than ALnico and Smco magnets but cheaper than them. 

 

In case you are wondering about the price then please send me a enquiry .

Do not forget to include the following information in your enquiry:

 

  1. Grade of the magnet(for e.g N35,N42,N45, N45 etc.You may choose from the table below)
  2. Size
  3. Shape(mostly seen shapes are Disc,Cylinder, Rectangular, tube etc..
  4. Direction of magnetization( most Neodymium magnetization are magnetized along their thickness; Please see the picture below for more explanation)
  5. Coating( mostly it's Nickel or Ni-Cu-Ni or Silver etc.. We also have Epoxy coating)

Below are pictures showing different kinds of magnetic orientation
