NdFeB Grade N38H Magnetic Performance Thermal performance Demagnetization curve introduction
There are many grades of neodymium magnets. For details, see the performance grade table of sintered neodymium iron boron magnets. Today we mainly introduce the 38H performance grade, including its magnetic performance, thermal performance, and demagnetization curve. I hope it will be helpful to those who want to know.
There is no difference in magnetic properties between 38H and N38. The main difference is that N38H can withstand higher temperatures, 120°C. I remember that many customers choose the magnetic steel on electric vehicles for this performance. 38H needs to add heavy rare earth elements (terbium, dysprosium) so the raw material The cost and process cost are higher.
