Ferrite Magnets Overview
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 Powerful Disc Ferrite Permanent Magnet
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.
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. ceramic permanent magnets
Is this magnet isotropic or anisotropic?
Our neodymium, ferrite and AlNiCo magnets are all anisotropic.
Some magnetic tapes and sheets are anisotropic and others are isotropic. You can find the specifications in the individual product descriptions.
The characteristic “anisotropic” or “isotropic” indicates if a magnet has a preferred magnetisation direction.
isotropic = no preferred direction anisotropic = has preferred direction
Magnetisation in any direction Magnetisation exclusively in the specified direction
Lower price Higher price
Lower adhesive force Higher adhesive force
