Special Ferrites

Ferroxcube has the ability to produce small production series of custom cores by CNC machining and with special processes, such as lathe, grinding, cutting or assembling. This capability enables the production of shapes not feasible by standard processes such as multi-axial cores and large cores used in scientific, high tech industrial and medical applications.

Special attention to be paid to the complete range of materials and shapes for particle accelerators, including 500 mm toroids, blocks and large P-cores.
