Permalloy
Permalloy
To improve resistivity and enhance processing performance, elements such as Mo, Nb, and Mn are often added to Fe-Ni binary alloys [1-3]. The appropriate amount of Mo can improve the magnetic properties of permalloy, reduce sensitivity to stress, and increase initial permeability. A small amount of Cu can improve the initial permeability and maximum permeability of permalloy, reduce its sensitivity to stress and temperature, and enhance its cold working properties. Si is a non-magnetic element, and an increase in Si content tends to reduce the saturation magnetic flux density.
