Because these are oxide magnets produced by the powder metallurgy method, their residual magnetic flux density is relatively low, but they have the major advantage of high coercive force and are therefore not easily affected by the presence of demagnetizing fields.
Positioning of Ferrite Magnets
Ferrite magnets use a wide range of materials with special properties. Especially at the high end of the performance spectrum, our magnet series are suitable for all kinds of applications.
HCJ and Br correlations of the various materials are shown in Figure 1.
Ferrite magnets may be customized upon request, within the indicated range of HCJ and Br characteristics.
In the interests of thorough quality control in each process, we have adopted measuring methods of the Magnetic Materials Producers Association (MMPA) of the United States and the Japanese Industrial Standard (JIS) for magnetic characteristics.
