Ferrite (HF) magnets

Hard ferrite magnets (HF) consist of magnetizable ferrite and are very cost-effective permanent magnets. They are known as hard ferrite magnets, ceramic magnets or ceramic permanent magnets. The advantage of ferrite magnets is that they last a long time even under extreme conditions, do not lose their static magnetic field and are not sensitive to chemicals, alkalis and salts.

The production of HF magnets often requires tools, therefore not every desired size is possible.
The surface is smooth, but not dust-free. The specified temperature is the maximum usage temperature of the material.
However, the shape can affect the strength
