Product Info

1、 Item name: thin block ferrite magnet

2、 Material detail:Ferrite powder,strontium,barium ,etc.

3、Characteristics: 

3.1、 Low cost, high-energy, good electric insulation and excellent resistance to demagnetization.

3.2、 High coercive force, high electric resistance, long-time stability, and economical price.

4、Type:Isotropic ferrite magnets; Anisotropic ferrite magnets

5、Application:Widely used in ammeter, speaker, audio, phone, TV, dynamo, DC permanent magnet motors (used in cars), etc

Manufacturing process:

1). Dry process:By dry process, can produce isotropic & anisotropic magnets. The tool can be changed and developed easily.

2). Wet process:By wet process, only anisotropic magnets can be produced. It is complicated to change the tool and the tooling charge is much higher.


Magnetization:

1). Isotropic ferrite magnets are not oriented and can be magnetized in any direction.

2). Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
