General Description
Mu 85 is a soft magnetic nickel-iron alloy with about 80% nickel, 5% molybdenum, a saturation induction of approx. 0.7 T, the highest technically obtainable permeability, and a very low coercive force.
Typical applications are toroidal tape-wound cores, laminations, shieldings, electromagnetic relays.
