Pomo Alloy
Pomo Alloy
To improve resistivity and process performance, elements such as Mo, Nb, Mn are often added to Fe Ni binary alloys [1-3]. The appropriate content of Mo element can improve the magnetic properties of PoMo alloy, reduce the sensitivity to stress, and increase the initial magnetic permeability. A small amount of Cu element can increase the initial and maximum magnetic permeability of PoMo alloy, reduce its sensitivity to stress and temperature, and improve its cold working performance. Si is a non-magnetic element, and an increase in Si content can lead to a decrease in saturation magnetic induction intensity.
Application areas:
Transformer
Leakage protector
Common mode inductor
Current transformer
Magnetic amplifier, etc
