N35 Grade Sintered NdFeB Magnet With Ni Coating
Quick Detail
Grade: N35-N52
Composite: Nd2Fe14B
Shape: block, ring, disc
Surface coated: Ni, Zn, NiCuNi, Epoxy
Certified: RoHS
Description
Sintered NdFeB magnets are produced by powder metallurgical process. Nd2Fe14B is the main element in Neodymium and gives Neodymium strong magnetic power. In fact its maximum RH is more than ten times that of Ferrite. Neodymium has good machinability properties and can work well at temperatures up to 200 degrees Celsius. It is usually coated with Zn, Ni, NiCuNi, Epoxy.
Application
They are widely used in motors, speaker, sensors, toys, electronic products
