Feature:
Is the most common form of ferrite ring magnetmaterial to powder metallurgy, materials are divided into into barium (Ba) and strontium material (Sr) two kinds, and is divided into anisotropic and isotropic, it is not a permanent magnet easydemagnetizationtype of corrosion is not easy, the maximum operating temperature up to 250ºC, more hard and brittle, with diamond cutting tools such as sand.

Application: 
Only alloy formation mold.A the permanent magnet motor (Motor) and the heavy use of products such as speakers (speaker) and other fields.
