Sintered NdFeB magnets greatly expand the applications of permanent magnets.They are widely used in the fields of transportation,energy,communications,home appliances,machinery and medical equipment and have become indispensible function materials in manufacturing and daily life.

Sphere neodymium magnets are ball shaped magnets,widely used in consumer electronics,magic,hobby,consumer products,R&D and industry applications.

Avaliable sizes of sphere NdFeB magnet

Relying on experienced production team and strong maching capability,most sizes of neodymium magnet can be produced with very high quality,and the tolerance can be controlled within +/-0.05mm or +/-0.1mm.The sizes of sphere neodymium magnet D5mm,D8mm,D10mm,D25 mm and customized sizes are available.

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.

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.
