The alloy, which is similar to the material 2.4545, is additionally subjected to a special annealing process in order to be able to score with the highest permeability values ​​even at 4 K.

Toroidal cores

In general, toroidal cores, which practically form an air gap-free magnetic circuit with a constant cross-section, allow the most advantageous use of the magnetic material properties.

Nickel 80

µMetal, ASTM A753 Alloy 4, alloy 2.4545. An alloy that contains nickel as its main component.


The laminations made from soft magnetic alloys are used for transducers, chokes and small transformers for decades.

Common mode chokes, CMC

Common mode chokes are useful for the prevention of electromagnetic interference (EMI) and radio frequency interface (RFI) from power supply lines and for preventing electronic equipment from malfunctioning.
