Features:

1.NdFeB magnets contain a large amount of rare earth elements neodymium, iron and boron.
2.Permanent magnet material with high magnetic energy accumulation and coercivity.
3.High cost performance and good mechanical properties.
4.Have excellent magnetic performance

Applications:

Widely used in permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment instruments, etc.

Notices:

1.Avoid placing NdFeB magnets near magnetic objects such as mechanical watches, monitors, etc.
2.Avoid the hands or other parts of the body are clamped by NdFeB magnets, for larger size magnets should pay more attention to personal safety and protection.
3.When using or keeping NdFeB magnets, avoid corrosive gases, highly conductive environments (e. containing electrolytes, acidic environments, organic solvents, etc. otherwise it will cause corrosion of NdFeB magnets and decrease of magnetic properties and mechanical strength.
