Is UH the grade of neodymium magnet? What is the difference between NdFeB UH and EH?

If there is UH behind the grade of magnet, it is a neodymium iron boron magnet with high coercivity.

How much is the temperature resistance of UH?

It can withstand 180 ℃ and can use this grade if it is less than this temperature.

What is the difference between NdFeB UH and EH?

The above figure shows the main magnetic property parameters of NdFeB 38UH and 38EH. It can be seen that there are still some differences. The remanence value of UH is larger, and the EH grade value is larger in terms of intrinsic coercivity.

The main difference is temperature resistance. The EH series brand magnet has higher temperature resistance and can withstand 200 ° C. It can be used in places with higher ring temperature.

In terms of the price of blank materials: the price of 38UH is about 455 yuan per kilogram, and the price of 38EH is about 530 yuan per kilogram.
