3.Shape:Block,Disc,ring,Segment,Arc,Cylinder,Round,etc.
4.Size: various according to clients' request.
5.Coating:Zn,Ni,NiCuNi,Sliver,Epoxy,etc.
Features:
1. high performance, cost ratio
2. high intrinsic coercive force after concocting
3. it can stand high working temperature, up to 200℃
4. it is prone to corrosion in humid environments, need surface treatment
5. quick delivery and good service
6. it is easily formed into various sizes

Application:
All These special features of NdFeB material make it irreplaceable in the world. So till now, they are widely used in electronics (sensors, microphone assemblies), aviation, motors (vibration motors, DC motors, servo motors and linear motors), automobiles, MRI/NMR, medical apparatus and transmission machine and even in many details of our everyday life.
