Why Neodymium Magnet?

 

Subsequent to Ferrite Magnets and Alnico Magnets, Neodymium Magnets as the third generation are the strongest magnets in the world due to the higher remanence,coercive force,and higher Max energy product, it even reaches 55MGOe(which is called N55)!

It is easily formed into various sizes, and widely used in mini-motors,meters,sensors,sound device,magnetic suspension system,magnetic transmission machine and iatrical apparatus and other applications. It is prone to corrosion in humid environments, usually need surface treatment according to different applications.

According to the different usage, temperature and application, neodymium magnets are classified to many grades, each grade corresponds to different magnetic field,magnetic flux,pull force etc.
