N55 Neodymium Magnets – Powerful new grade of Neodymium added to our magnet offerings
A powerful new grade of Neodymium is now available at MPCO 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.
Sintered Neodymium Iron Boron (NdFeB), or “neo” magnets, is the third generation of permanent magnet developed in the 1980s. It offers the strongest magnetic power today. With its excellent magnetic characteristics Neodymium Magnet offers flexibility for new designs or is replacing older materials like Alnico and Ceramic in many applications, including high performance motors, brushless DC motors,
High Anti-corrosion and Low Weight Loss Neodymium Magnet
USA PCT: 121±1℃, 2 atm, 95% RH, 96 hours, weight loss less than 5~10mg/cm2
Europe HAST: 130±2℃, 3 atm, 95% RH, 168 hours, weight loss less than 2~5mg/cm2
Due to special material formulation and manufacturing process, the corrosion resistance is so excellent that neodymium magnet can reach the strict testing requirements above.
Application of Neodymium Magnet
These neodymium magnets are widely used in motor, sensor, elevator, automotive, wind generator, speaker, military and aerospace industries etc.
Performace at high temperature Neodymium Magnet
With higher Hcj value, these neodymium magnet is more stable during high temperature. The tests show that the maximum permanent loss after aging is 5%.
Available N55M stock magnets
We stock seven sizes of N55M Neodymium Magnets (Please contact us if you require a custom size):
0.125” dia 0.060” Lg
0.125” dia 0.125” Lg
0.187” dia 0.060” Lg
0.250” dia 0.125″ Lg
0.250″ dia 0.250” Lg
0.312” dia 0.250″ 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
Selecting the proper grade of material for your application is key to the performance of your product. Refer to our guide on “How to choose a magnet grade” for more considerations that may influence this decision. You can also use our Demagnetization/Permeance Coefficient Tool and our Neodymium Magnetic Pull Force Calculator to test against different variables, including your material grade.
To determine if N55M is the best grade for your application, contact our team at MPCO Magnetics to discuss your project needs. Utilize our years of magnet experience and engineering expertise to help you find the best solution for your product design and budget. 620LBS*2 Neodymium Double Sided Fishing / Searching Eyebolt Magnet
