Powerful new grade of Neodymium added to our magnet offerings

N55 Symbol

A powerful new grade of Neodymium is now available at Dura Magnetics: 55 MGOe Neodymium. As the strongest rare earth magnetic material available for commercial use, N55M is about five- to six-percent stronger than N52 MGOe, our previously highest available grade.

Available N55M stock magnets

We stock seven sizes of N55M (Please contact us if you require a custom size):

0.125” dia0.060” Lg
0.125” dia0.125” Lg
0.187” dia0.060” Lg
0.250” dia0.125" Lg
0.250" dia0.250” Lg
0.312” dia0.250" Lg
0.375” dia0.125" Lg

N55M has a maximum operating temperature of up to 80 degrees Celsius. With a strong magnetic field, this grade of Neodymium is preferred for holding force applications that have size or space limitations.

Order N55M for your application
