How Does Temperature Affect Alnico Magnets?

WebAlnico magnets can continue to be effective, event when heated to the point of glowing red-hot! Alnico magnets are also generally good performers in low temperatures down to approximately -70 oC -100 oC. Some grades actually increase their resistance to demagnetisation as they get hotter by small amounts from ambient temperature. Max. WebRegular neodymium magnets are strongest operating up to temperatures of 80°C but after this point, they will lose their magnetic output. On the other hand, grades with a ‘VH/AH’ rating can operate in temperatures up to 230°C. See the table below for maximum operating temperatures of each grade. flowers generator
