Magnet Shape
The sintered ferrite magnets are available in isotropic magnet and anisotropic magnet.
The sintered ferrite has high hardness. It means that can only used diamond tools cutting, grinding techniques can be used to manufacture these products. Attention is required during production & transportation due to their brittle nature.
Application field
The sintered ferrites have widely applications due to their low cost and simple manufacturing process; The applications include permanent motors, DC motor, loudspeakers, reed switch operation, magnetic separator assemblies and holding devices etc.
