*Ferrite:

 Ferrite is an oldest magnet mauterial and also is most  widely used at present It is also called black 

mangnet.Its maximum magnetic energy is low,but its excellent temperature proof,steady property,cheap price

determine its wide usage in the speakers,motors,sensors,medical devices.

  In order to suit the export,we have set up our own ferrite production base in JiaXing and Dongyang.The annual output has reached over 10,000 tons.
