Precision Alloy 1J85
Soft magnetic alloys are nickel-iron alloys that contain from about 35 to 81% of nickel
Precision alloy 1J85 is a magnetic alloy composed of 80% nickel and 15% iron, with small amounts of copper, manganese, and silicon. It has a high magnetic permeability, low coercive force, and low hysteresis loss, making it ideal for use in high-precision electronic and electrical equipment. It is commonly used in magnetic heads, magnetic shielding, and transformers. Its unique properties make it suitable for use in applications that require high magnetic sensitivity, such as magnetic sensors and magnetic memory devices.
Characteristic as below:
(1)high permeablity
(2)high saturation magnetostriction
(3)low hysteresis-energy loss
(4)low eddy-current loss in alternating flux
(5)low curie temperature
(6)vonstant permeablity with changing temperature
Application field:
(1)instrument transformerd
(2)rader pulse transformers
(3)Transducers
(4)Shielding
(5)tape recorder head laminations and so on
