Bonded    Ferrite

These magnets are obtained from a mixture of Ferrite powder together with polymer.

A subsequent processing (calendering) results in flexible, oriented and non-oriented sheets and "strips" even of irregular shape (extrusion).

With different alloying elements and different productive processes (pressing or injection), it's possible to make parts of complex shape with high mechanic precision.

Also available in sheets or magnets with PVC of different colour or biadhesive on one side.
