ferrite magnet  are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. Anisotropic grades are oriented in the manufacturing direction and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction.

 

The chemical composition is SrO-6(Fe₂O₃), strontium hexaferrite. The raw materials used to produce ferrite magnets are strontium carbonate and iron oxide both of which are readily available and low in cost. As a result, the use of ferrite magnets in most applications is more economical than other materials.

 

Advantage
1.Cheapest magnet material
2. Good anti-corrosion performance, no surface treatment needed
3.Excellent temperature stability
4.Compact crystal
5.Could provide isotropic and anisotrpic

Two 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.
