The magnetic material that is often used as a permanent magnet is
These are the main market of permanent magnetic materials, and some from the original production process or cost reasons, can not be applied widely and eliminated, such as Cu-Ni-Fe (Tong Nietie), Fe-Co-Mo (Tie Gumu), Fe-Co-V (FeCoV), MnBi (Mn BI)
The second category is ferrite permanent magnet (Ferrite)According to the production process, they are divided into sintered ferrite, bonded ferrite and injection ferrite, and these three processes are divided into equal and heterogeneous magnets according to the orientation of the magnetic crystal.
The first is: alloy permanent magnetic materials, including rare earth permanent magnet materials (NdFeB, SmCo, Nd2Fe14B) (SmCo), aluminum nickel cobalt (AlNiCo)
