Characteristics :
* Low cost, high-energy, good electric insulation and excellent resistance to demagnetization.
* 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.

Hard Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets has good resistance to demagnetisation and corrosion, Due to their low cost, Ferrite magnets enjoy a very wide range of applications, from motors and loudspeakers to toys and crafts, occupy about 75% of the world market of constant magnets. we can supply you with both wet-pressed anisotropic and dry-pressed isotropic grades in all shapes and sizes. Multipolar Ring Sintered Ferrite Ceramic Permanent Magnet
