Precision Alloy 1J79
Soft magnetic alloys produced by Shanghai Phoenix Alloy are nickel-iron alloys that contain from about 35 to 81% of nickel. 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.
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.
