Neodymium-Iron-Boron magnets: neodymium Iron Boron magnet with the highest yet discovered are commercial properties, known as magnetic King, has a very high magnetic properties of the maximum energy product (BHmax) higher than ferrite (Ferrite), 10 times more than double. Very good machining properties of its own. Operating temperature up to 200 degrees Celsius. But its hard, stable performance, good price, however, and their application is extremely useful. But because of their chemical activity is very strong, so it is necessary to coat the surface layer.

      ND-Fe-b permanent magnet material is based on intermetallic Nd2Fe14B magnets. Relative to the casting Department of Al-Ni-Co permanent magnets and ferrite magnets, neodymium Iron Boron has a very high magnetic energy product and coercive force, can lift the equivalent weight of 640 times times its own weight.
