Nickel/Iron Alloy Foil (Ni80/Fe20) is a form of foil with a nickel to iron ratio of 80% to 20%. This alloy foil offers properties such as good corrosion resistance and magnetic permeability. Possible applications of the nickel-iron alloy foil include use as a construction material in corrosive environments and in magnetic sensors or shielding. This nickel-iron foil is part of Goodfellow's range of specialty metal foils, providing unique properties not found in pure nickel or iron alone.
