Description

Ferrite magnets have good anti-corrosion performance, no surface treatment needed. There are two manufacturing process for ferrite magnets: dry process and wet process. By dry process, can produce isotropic & anisotropic magnets; by wet process, only anisotropic magnets can be produced. Isotropic ferrite magnets are not oriented and can be magnetized in any direction; anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation. For dry process, the tool can be changed and developed easily, while for wet process, it is complicated to change the tool and the tooling charge is much higher. At present, we have put our emphasis on arc segment magnets for electric motors, disc magnets and block magnets for special applications
