Introduction
Ohmalloy-1J46 is a Ni-Fe soft magnetic alloy, and its main compositions are 50% Ni, 48% Fe and other micro-elements. It has features of high magnetic permeability, higher saturation induction density, etc. As a soft magnetic material used in alternating current, due to the alternating magnetization, vortex is induced inside the material, producing loss. The smaller the resistivity and the greater the thickness of the alloy, and the higher frequency under the alternating magnetic field, the greater the eddy loss and the more the decrease of the magnetic performance. Thus, the material must be machined as thin sheet (strip) and coated with insulation layer on the surface. Or adopt certain method to form oxide insulation layer on the surface, and such alloys usually adopt magnesium oxide elecrophoretic coating.

Application
This magnetic alloy is mainly used in high magnetic conductivity yoke iron, sensitive relay, low loss micromotor, low power transformer, pulse transformer, transistor switch, magnetic amplifier, magnetic modulator, sensitive signal input and output transformer, magnetic sensor of aviation magnetic heading instrument, magnetic sensitive element of magnetic measuring instrument, stator and movable plate of precision electric meter, magnetic shielding and magnetic temperature compensating elements.
