Amorphous cores for advanced magnetic applications

High-performance Iron and Cobalt alloys for advanced applications

Only a select few Iron and Cobalt-based alloys hold significant technical and commercial relevance today. These alloys, produced as thin ribbons, can be shaped into various forms, including toroids, oval or rectangular shapes, E-cores, bars, and plates, making them highly versatile for numerous applications.

Cobalt-based alloys boast the best soft magnetic properties, making them ideal for use in current transformers (CT), high-quality signal transformers, filters, magnetic amplifiers (MagAmps) in Switched Mode Power Supplies, spike killers, and other specialized applications.

Our standard Iron-based material offers a contemporary and efficient alternative to electrical steel (Iron-Silicon). It is primarily used in 50/60Hz transformers and chokes for medium frequency and small ripple applications.

At our Magnetics Products Technology Centre, managing the Acal BFi kOr brand, we support you in selecting the right material, shape, and finish, and develop customised products quickly and efficiently to meet your specific needs.
