N42SH, N42, they are all neodymium magnets (neodymium iron boron), as for why the front has the suffix SH and the back does not, what is the main difference between the two, some friends are not very clear, because there is no article on their differences on the Internet., the permanent magnet manufacturer Courage Xiaofu will introduce to you next.
What is the difference between NdFeB n42 and 42sh material?
The main difference is the temperature resistance, Magnetic force is similar, The dysprosium content is different. The metal dysprosium content added to the SH grade NdFeB grade is: 1-4.5%. The grade sh has better temperature resistance and is mostly used in the motor field.
Comparison of magnetic properties between N42 and N42SH grade neodymium magnets
The highest grade of neodymium magnets currently available is N52, and any letter after the grade refers to the temperature rating of the magnet.
Is it reasonable that NdFeB n42 is two points less efficient than n42SH?
It is reasonable. According to the sintering principle, the raw materials used for high temperature resistance are different, because we are not in the maximum area when we use it, and N42SH is more efficient in a certain range.
Choose N42 grade or n42sh?
This mainly depends on where your magnets are used. If the normal environment is N42, there is no need to waste money (the price of N42 grades of the same size will be higher).
The above is about the introduction of Neodymium Magnet Grade N42SH vs N42, do you understand?
