What are the mainstream of permanent magnets

Permanent magnets may not be maintained by the current magnetic field , the magnetization can be maintained by a constant magnetic , so called permanent magnets. It has as high coercivity , remanence and maximum energy product , the maximum magnetic energy can be stored and the most stable magnetic properties. As to what the mainstream of the permanent magnet , then this article is to talk about the rare earth permanent magnet materials, according to different process , there are three : Bonded NdFeB sintered NdFeB, NdFeB injection . The following detailed explanation of these three permanent magnets .
Bonded NdFeB NdFeB powder is mixed by resins, adhesives and plastics , and then compress them , injection molding or extrusion methods, this composite NdFeB permanent magnets can be molded once , do not the second process , a number of complex shapes can also be a shape, it is characterized by high precision, good magnetic properties , corrosion resistance, temperature stability.
Sintered NdFeB powder is made ​​by a jet mill and then smelting , which is characterized by exceptionally high coercivity magnetic energy is also very high , more than 10 times higher than ferrite , but it requires coating will not rust coating to protect it .
Injection NdFeB is characterized by high accuracy , easy molding , all kinds of bizarre thin ring can be made .
