How much stronger is N55 neodymium magnet than N52?

The theoretical (BH) maximum value of NdFeB magnet is 512kj / m3 (64mgoe). At present, most magnet manufacturers can produce n52 magnets. The (BH) max of n52 has reached 90% of the theoretical limit. The question in the minds of many users is, is there a stronger level than the N52 magnet? Today, I’d like to introduce you to Xiao Fu.
N55 magnet is the strongest commercial magnet. The strength of rare earth NdFeB magnet is measured in the range of 24mgoe-55mgoe, which is 5-6% stronger than N52.
How high is the temperature resistance of N55 NdFeB magnet?
In order to ensure that N55 magnet has ideal saturation magnetization, manufacturers will no longer use heavy rare earth and other metal elements to improve the coercivity of the magnet. The maximum working temperature of N55 magnet is only about 60 ℃.
