Neodymium Magnet (also know as NdFeB, NIB or Neo Magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the ND2Fe14B tetragonal crytaline structure.
Neodymium magnets are the strongest type of permanent magnet made. They have replaced other types of magnet in the many applications in modern produces that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.
Grades of Neodymium magnets
N35-N52(working temperature Max. 80)
33M-48M(working temperature Max. 100)
30H-45H(working temperature Max. 120)
30SH-42SH(working temperature Max. 150)
30UH-35UH(working temperature Max. 180)
28EH-35EH(working temperature Max. 200)
Some important properties used to compare permanent magnets are: Remanence(Br). Which measures the strength of the magnetic field; Coercivity
(Hci), the material's resistance to becoming demagnetized; Energy product(BHmax), the density of magnetic energy; And Curie temperature(TC), the temperature at which the material loses its magnetism. Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Neodvmium is alloved with terbium and dysprosium in order to preserve its magnetic properties at high temperatures. The table below compaes the magnetic performance of neodymium magnets with other types of permanent magnets.
Application of neodymium magnet:
Magnets are found in almost all modern objects. The computer hard drive Most modern mobile phones now include a small neodymium magnet or two. Like computer compenents magnets have gradually become small and smaller making them easy to integrate into most industrial manufacturing processes. We also find that a lot of model and jewelley makers like our magnets as they fit easily into their models and allow parts to be easily removed and re-attached. For lifting. Holding, separating, and retrieving, we have the right magnetic assemblies and permanent magnetic materials for all types of industrial, OEM and commercial applications. Our expertise and ability to develop customized solutions will match the correct magnet for your application.
