At different temperatures, how to choose NdFeB high temperature magnet

- Nov 04, 2017 -


General neodymium iron boron magnets in the working temperature reaches 80 degrees above the time demagnetization, and some characteristics of the temperature is very high, much higher than 80 degrees, then for different high temperatures, how to choose neodymium iron boron High temperature magnet how to buy high temperature magnet?

First, at the working temperature of 80 degrees - 230 degrees choose NdFeB high temperature magnets, the specific grades are as follows:

1, at 80 degrees - 100 degrees between the operating temperature, you can use M file NdFeB high temperature magnet

2, at 100 degrees - 120 degrees between the operating temperature, you can use H-file NdFeB high temperature magnet

3, at 120 degrees - 150 degrees between the operating temperature, you can use the SH file NdFeB high temperature magnet

4, at 150 degrees - 180 degrees between the operating temperature, you can choose UH file NdFeB high temperature magnet

5, at 180 degrees - 200 degrees between the operating temperature, you can use EH file NdFeB high temperature magnet

6, at 200 degrees - 230 degrees between the operating temperature, you can use AH file NdFeB high temperature magnet

Second, the working temperature of 230 degrees - 350 degrees choose SmCo high temperature magnet, the specific grades are as follows:

1, at 230 degrees - 250 degrees between the operating temperature, you can choose 1: 5 samarium cobalt

2, at 250 degrees - 350 degrees between the operating temperature, you can choose 2:17 samarium cobalt


Third, the working temperature of 350 degrees above the operating temperature of the high temperature magnet can only choose Alnico magnet.
