These alloys are using in applications requiring the following characteristics: high permeability, high saturation magnetostriction, low hysteresis-energy loss, low eddy-current loss in alternating flux, low curie temperature, vonstant permeability with changing temperature.Soft magnetic alloys produced by Shanghai Phoenix Alloy are nickel-iron alloys that contain from about 35 to 81% of nickel. 


 


Shanghai Phoenix Alloy has been manufacturing soft magnetic alloys for many years. They are used for instrument transformers, radar pulse transformers, transducers, shielding, tape recorder head laminations and so on.
