Different grade of sintered neodymium magnet
Basis on different temperature resistrance,the neodymium magnet are divided into N,M,H,SH,UH,EH,AH series,and the corresponding maximum operating temperature is 80℃,100℃,120℃,150℃,180℃,200℃,220℃.
In the same serires,the higher the grade of NdFeB magnet,the more magnetism it is.For example,in N series,N52 grade have more magnetic power than N35 grade,and the N55 grade is the strongest one.
For initial projects,we are happy to provide magnetic technology support and made magnet samples according to your requirements for prototyping or testing needs.
Check the grade/properities of sintered neodymium magnet.

Surface treatment of sintered neodymium Magnet
For general use,zinc and nickel plating are most common,and the salt spray test can reach 24 hours to 48 hours.
Epoxy or NiCu+Epoxy Coating have a better corrosion resistance,the salt spray test can reach 72 hours.
