When we buy the neodymium magnet, we need to know three core information, magnet grade, working temperature range, surface coating.
- Magnet grade
Magnet grade is the identification for the sintered NdFeB magnet, eg, N25, N52. When the number is bigger, the BHmax is higher. However bigger magnet grade is not means that it could anti high temperature. If you would like more detailed information, contact me on the website. We will send you detailed information.

Working temperature range
Normally N series is 80-100℃,H series is 120℃,SH series is 150℃,UH series is above 200℃.If your product used in motor or sensor, you need to check the highest temperature.
If you purchase the magnet, just tell me your working temperature, we will introduce magnet grade.
- Surface coating
All the sintered NdFeB magnet need surface coating, we could introduce you different coating according to your working environment. Normally standard nickel, black nickel, gold plating, zinc plating, epoxy coating, tin coating, electroless nickel. We will choose the right surface coating according to your working environment. We will also provide salt spray test report.
