View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.MAGNIFER 7904 is a soft magnetic nickel-iron alloy containing about 5% molybdenum. It offers extremely high permeability, very low coercive force and minimum hysteresis loss. It is used primarily for transformers, tape-wound troids, laminations, shielding and relay parts.
