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

    Type:
    Isotropic ferrite magnets
    Anisotropic ferrite magnets

    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.
