Sintered NdFeb（ネオジム鉄ホウ素） is one of the highest performance permanent magnet materials at present.              

      With its appearance,many hightech products have appeared,especially in the application of motors,which makes many products develop towards miniaturization and minaturization.The high remanence,high coercivity and high magnetic energy product of sintered NdFeb make it widely used in servomotors、flat brushless motors in progressive motors、IT products 、nuclear magnetic resonance、speakers and other products.

       NdFeb is easy to rust and oxidize,so its surface is usually electroplated,such as nickel、zinc、silver、gold etc.It can also be phosphagted or sprayed  epoxy resin to slow down its oxidation rate.
