On the move with soft magnetic Ni-Fe-alloys

摘要

With the growing importance of Electro Mobility (eMobility) and the use of electric powertrain technologies (in combination with an increase of electrical/digital equipment), the demand for effective shielding materials as well as sensors is on the increase. Nickel-containing materials are playing a crucial role in this growing field of application. Nickel-based alloys are well known for their corrosion-resistance and their high temper- ature strength. However, some of them have even more to offer. Nickel-iron alloys form the group called soft-magnetic alloys. Soft-magnetic nickel- iron alloys can easily be magnetised and demagnetised. Their magnetic properties, coercive force, permeability and hysteresis losses are clearly superior to those of the iron materials.
