Iron-nickel cores (Fe-Ni), Mumetal
We are also able to supply Fe-Ni alloy cores in strip thicknesses of 0.10 mm and 0.20 mm. The property of higher initial permeability makes Fe-Ni alloys particularly suitable for the construction of measuring transformers, differential transformers, magnetic amplifiers, filters and in many cases for shielding field leakage. The use of state-of-the-art instruments for continuous testing during production guarantees the required magnetic properties of these products.
