Neodymium Magnets (NdFeB Neodymium Iron Boron)

 

The neodymium magnets were invented in 1980s. The major components of neodymium magnets are neodymium (Nd), Iron (Fe) and Boron (B). Since neodymium is one of the rare earth elements, it is also called rare earth magnets. Currently the rare

earth magnets are majorly referring to neodymium magnets even though Samarium Cobalt also contains rare earth elements.

Neodymium magnets found more and more applications in all industries and daily life majorly because it presents an extraordinary high gauss ratings so is MGOe values comparing to other types of permanent magnets. High gauss ratings improve the products’ performance or reduce the size of the products significantly.

Neodymium magnets are graded with N values or Maximum Energy Product. It started with grade N22 initially but very few manufacturers are now making the grades lower than N35. Currently, the available grades are N35, N38, N40, N42, N45, N48 , N50 and N52 even though any custom grades can be made. N52 means the Maximum Energy Product of the material is 51-53 MGOe.

As the third generation rare earth magnets, neodymium magnets provide the highest Maximum Energy Product of all the permanent magnets.
