Grade N55 Neodymium Magnets — The Highest-Performance Commercial Rare Earth Magnets
N55 is the highest sintered neodymium magnet grade currently in commercial production, offering a maximum energy product (BHmax) of approximately 55 MGOe — roughly 6–10% stronger than N52 grade at equivalent dimensions. JC Magnetics stocks N55 disc and cylinder magnets for engineers and researchers who require every available unit of magnetic performance. N55 magnets are specified in high-flux-density motor designs, advanced magnetic bearing systems, research apparatus, and precision sensor calibration fixtures. Due to the high iron content of N55 alloy, operating temperature should be kept below 80°C for sustained performance. Available in disc and cylinder profiles.
