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.Isotropicferrite 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.
