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
