Ferrite
magnets are essentially composed oxide materials with
BaCo3 (barium carbonate) or SrCo3 (Strontium carbonate). |
|
|
It is manufactured under a powder metallurgy process and
classified into two types: Isotropic and Anisotropic.
Isotropic is molded in absence of a magnetic field. Anisotropic
can be further divided into "wet" and "dry" depending
on pressing methods. |

Excel
corrosion resistance and good resistance to demagnetization.

The
tolerance is generally approximately + or - 0.2mm though
it still depends on magnet shape. For a special application,
the dimensional tolerance could be reduced to + or -0.05mm
by grinding after machining process. |
