产品说明
Magnifer 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 Magnifer 7904 are:
  • Toroidal tape-wound cores - integrating current transformers 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
  • Shieldings - 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
