Nickel Steels use 30 to 80% Nickel to greatly reduce the core loss and increase permeability compared to Grain Oriented steels. Because of their low core loss, they are used at high frequencies ranging 1000 to 100,000 Hz. But their saturation flux density is lower than that of electrical steels. The 80% Nickel steels offer higher permeability but lower saturation (~0.8 to 1.1T). The 50% Nickel steels offer higher saturation (~1.6T), but have lower resistivity. But as with electrical steels, trace impurities (that impact magnetic properties) differ from manufacturer to manufacturer. So MagWeb lists properties of these materials by the manufacturer, irrespective of they being of same composition. They are employed in inductors, transformers used in communication, EMI Shielding and anti-shop lifting industries.
