... MAGNIFER 75 is a soft magnetic nickel-iron alloy containing about 5% copper and 2% chromium. It offers very high permeability, very low coercive force and minimum hysteresis loss. It is used primarily for transformers, tape-wound toroids, laminations, shielding and relay parts. This datasheet...
