Magnifier 7904 soft magnetic nickel-iron alloy perm-alloy strip
General introduction:
-
Magnifier 7904 is a soft magnetic nickel-iron alloy with about 80 % nickel, 4.2 - 5.2 % molybdenum, a saturation induction of approx. 0.8 T, the highest technically obtainable permeability and a very low coercive force
-
Typical applications of magnifier:
-
Toroid tape, wound cores, integrating current trans-formers for earth-leakage circuit breakers, instrument transformers & inductive components
-
Laminations, transformer laminations, transformer cores for modems with special transformer characteristics, stamped rings for electronic earth-leakage circuit breakers
-
Shielding to protect against magnetic interference, in the form of shielding films, shielding cans and spatial shielding arrangements
-
Stepping motors stamped parts for analogue watch mechanisms
-
Relay parts components for electromagnetic relays
-
Other solid components with a low coercive force
-
We supply magnifier 7904 strip with thickness range 0.1~5mm and width up to 200mm
