Generally, hard ferrite magnets can therefore be used without additional corrosion protection. Isotropic magnets are shaped by compressing. Anisotropic magnets are compressed within a magnetic field. This provides the magnet with a preferential direction and triples its energy density. In contrast to AlNiCo magnets, hard ferrites are characterized by flux densities but high coercive field strengths. This results in the generally flat shape of the materials. Barium ferrite and strontium ferrite are differentiated depending on the starting material.
