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.Hiperco 50A is an iron-cobalt-vanadium soft magnetic alloy possessing high magnetic saturation, high direct current (dc) maximum permeability, low dc coercive force, and low alternating current (ac) core loss.
