The grades of different series of neodymium magnets are distinguished by adding letter suffixes after the basic brand. The following is a complete series grade introduction:
N series: ordinary temperature grade, the maximum working temperature is 80℃, the brands include N35, N38, N40, N42, N45, N48, N50, N52, etc.
M series: the maximum working temperature is 100℃, the brands are N35M, N38M, N40M, N42M, N45M, N48M, N50M, etc.
H series: the maximum working temperature is 120℃, the brands include N35H, N38H, N40H, N42H, N45H, N48H, etc.
SH series: the maximum working temperature is 150℃, the brands are N35SH, N38SH, N40SH, N42SH, N45SH, etc.
UH series: The maximum operating temperature is 180℃, and the grades include N35UH, N38UH, N40UH, N42UH, etc.
EH series: The maximum operating temperature is 200℃, and the grades include N35EH, N38EH, N40EH, etc.
AH series: The maximum operating temperature is 220℃. There is less information about common grades at present, and the specific grades may vary from manufacturer to manufacturer.
Neodymium magnets produced by different manufacturers may have certain differences in specific grades and performance parameters. In actual applications, it is necessary to select the appropriate grade of neodymium magnets according to specific usage scenarios and requirements.
