Neodymium iron boron temperature resistance grade

Neodymium Magnet Temperature Grades (100 Words)

1. Standard Grades

   • N Series (e.g., N35-N52): Max working temperature 80°C (no suffix) 127.

   
   

2. High-Temperature Grades

   • M: ≤100°C, H: ≤120°C, SH: ≤150°C, UH: ≤180°C, EH: ≤200°C, AH: ≤220°C 178.

   
   

3. Key Notes

   • Exceeding temperature limits causes irreversible demagnetization 14.

   • Material additives (e.g., Dysprosium) improve thermal stability 34.

   
   

For precise selection, match grades (e.g., N35SH) to application temperatures 6.
