Description
We have rich experience in supplying Europe motor users, we have
TS****9 certified. We had pleased to supply full set of PPAP
reports with samples to you
Ferrite (ceramic) magnets are essentially composed of oxide
materials with barium carbonate or strontium carbonate,
manufactured under a powder metallurgical process
The feature of low recoil permeability, along with the high
coercive force, makes them highly resistant to demagnetizing
fields. In addition, their relatively low specific density and
economical cost are also very attractive to the magnet designers.
When designing the ferrite magnets for a particular application,
primary consideration should be given to its shape limitation due
to the powder metallurgical manufacturing process and the
temperature dependence of ferrite materials
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
