(Common Name: Ni80Mo5, E11c, permalloy, 79HMA, PCS)
1J85 is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content. Invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields. Commercial permalloy alloys typically have relative permeability of around 100,000, compared to several thousand for ordinary steel.
In addition to high permeability, its other magnetic properties are low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications, allowing it to be used in thin films where variable stresses would otherwise cause a ruinously large variation in magnetic properties. Permalloy's electrical resistivity can vary as much as 5% depending on the strength and the direction of an applied magnetic field. Permalloys typically have the face centered cubic crystal structure with a lattice constant of approximately 0.355 nm in the vicinity of a nickel concentration of 80%. A disadvantage of permalloy is that it is not very ductile or workable, so applications requiring elaborate shapes, such as magnetic shields, are made of other high permeability alloys such as mu metal. Permalloy is used in transformer laminations and magnetic recording heads.
1J85 is widely used in radio-electronic industry, precision instruments, remote control and automatic control system.

1J85 precision alloy uses
1J85 is generally used in alternating magnetic field. Because alternating magnetization is the eddy current loss inside the material, the smaller the resistivity, the greater the thickness, and the higher the frequency in alternating magnetic field, the greater the eddy current loss and the lower the magnetic properties. Therefore, the material must be made into thin sheets (ribbons), and coated on the surface of the insulation layer, or the use of a certain method to form a surface oxide insulation layer. Usually 1J85 uses Magnesium Oxide electrophoretic coating.
