1J85 is a kind of Fe-Ni soft magnetic alloy with high weak permeability.Permalloy 80 is an alloy of nickel, iron and molybdenum. It is a soft magnetic alloy with exceptionally high magnetic permeability. The alloy has a low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications,where variable stresses in thin films would otherwise cause a ruinously large variation in magnetic properties.

chemical composition:

Characters:

High permeability and low coercivity in weak magnetic field.

Applications:

It is used widely Electro-magnetic shielding,specialty transformer laminations,toroidal tape wound cores,high quality motor laminations,stepping motor..

And widely used in radio electronics industry, precision instruments and meters, remote control and automatic control systems.

Available Forms and size: Bar, Strip, Sheet and Plate.
