Soft magnetic Iron-Nickel-Alloys
Brief description
The term soft magnetic strip stands for FeNi-alloys with a Ni-content of 35 - 81 %.
The Normaperm-Alloy (35 - 40 % Ni) stands out by its particularly low rise in permeability in the range of magnetic field strengths of up to 100 mOe.
Alloys with a content of 45 - 55 % Ni show a relatively good initial permeability and a high saturation induction.
Alloys with a content of 76 - 81 % Ni have high initial permeability values.
Applications
This group of alloys is used for DC relays as well as core laminations for transformers and chokes in communication and electronic facilities. Another field of application for alloys with 76 - 81 % Ni-content is the magnetic shielding of devices, components, or control elements.
