Neodymium Iron Boron, NdFeB, magnets are the strongest magnets available.
Like Samarium Cobalt, NdFeB is termed a Rare Earth magnet. The Neodymium Iron Boron, NdFeB, magnets are made of an alloy primarily consisting of Neodymium, Iron and Boron and the alloy is chemically written as Nd2Fe14B. Although Neodymium Iron Boron is often written as NdFeB or Neodymium, it is often given the nickname of "Neo" and, very infrequently, "NIB".
If the user understands the limitations of NdFeB and understands their application, the use of NdFeB magnets can allow very compact designs with high performance with issues affecting the performance. For note, if the magnet is kept in dry conditions at all times and the plating is not broken and no external demagnetising fields are applied to it, the magnet theoretically can retain its magnetism indefinitely.
The max operation of neodymium magnetNdFeB magnet have different grade from N35-N52.The higher grade,the stronger magnetic force.ALso the max working temperature from 80 to 230 degree,from N to UH.Different grade with different working temperature.N-80C,M-100C,H-120C,SH-150,UH-180,EH-200,AH-230
The coating of NdFeB magnet
All the Neodymium Iron Boron, NdFeB, magnets are prone to corrosion (a method similar to rusting). Usually haveZn,Ni,NiCuNi,Epoxy,Chrome,Gold,Silver and so on.
The application of magnetsNoeydmium magnet widely use in the different industry,such as Sensors,Magnet Motor,Wind Turbines Magnet,Wind Generators,Permanent magnet generator,Permanent neodymium magnets,Loudspeakers,Magnetic hooks,magnetic holder,
