Rare earth bar neodymium magnet with holes

We focus on Sintered NdFeB magnet and develop it under experienced engineer and passionate&studious sales team.
* Physical advandages:
This material is hard,brittle and it is easy to get corroded,but in order to protect the surface,we have lots of surface treament ,like Nickel,Nickel-Copper-Nickel,Znic,Black&Grey epoxy coating,Aluminium coating,Tin,Silver ect coating.
It is with high stability even it is under high temperature,the working stability is under 80degreeC for low Hcj,and above 200Degree C for high Hcj.The temperature coefficients -0.09--0.13% of Br,and -0.5--0.8%/degree C of Hcj.
