In the electronics industry, 1J85 cores are mainly low or medium alloys with high magnetic permeability and low coercivity. At high frequencies, materials with higher resistivity should be made on thin strips or alloys. Usually in sheet or strip form.   It is composed of nickel and molybdenum doped in different proportions of iron alloys. It is mainly used in two fields: energy conversion and information processing.   In the electronics industry, it is mainly low or medium alloys with high magnetic permeability and low coercivity. At high frequencies, materials with higher resistivity should be made on thin strips or alloys. Usually in sheet or strip form.   As a soft magnetic material used for exchange, due to the induction of AC magnetic eddy currents in the material, losses are caused. The smaller the resistance of the alloy, the greater the thickness, the higher the frequency of the AC magnetic field, the greater the eddy current, the greater the current loss, and the more magnetic loss. For this reason, the material needs to be made into a thinner sheet (tape) and an insulating layer is coated on its surface, or an oxide insulating layer is formed on the surface using certain methods. This type of alloy is often used for oxidation electrophoresis coating. Iron-nickel alloys are mainly used in alternating magnetic fields, mainly for yokes, relays, small power transformers and electromagnetic shielding. Permalloy is a nickel-iron magnetic alloy with a nickel content of about 80% and an iron content of about 20%. It is known for its relatively high magnetic permeability, which makes it useful as a core material in electrical and electronic equipment, and can also be used as a magnetic shielding material to shield magnetic fields.   Commercial Permalloy generally has a relative magnetic permeability of about 100,000, while ordinary steel has a relative magnetic permeability of 1J85. The 1J85 core metal shield is a soft ferromagnetic alloy, so it does not acquire remanence after the external magnetizing force is removed. It has high initial and maximum magnetic permeability with nominal hysteresis loss. It has small coercivity, rated core loss and small remanence. To obtain the required magnetic function, Mu metal should be heat treated at 1100℃ to 1180℃ in a dry hydrogen condition furnace below – 40℃ for 2 to 4 hours. This heat treatment increases the magnetic permeability by 40 times. Precision alloys have excellent physical and mechanical properties and are used in key components and devices of precision motors, electrical appliances, instrumentation, telecommunication equipment and precision machinery. According to the use and characteristics, precision alloys are divided into hard magnetic alloys, soft magnetic alloys, elastic alloys, expansion alloys, thermobimetals, resistance alloys, thermocouple alloys, conductive alloys, electrical contact alloys, shape memory alloys, superconducting alloys and so on. The main part of the fluxgate sensor is the magnetic core, whose hysteresis characteristics affect the performance of the sensor. When modeling a fluxgate sensor for design purposes, a prepared model of the core's hysteresis characteristics is required to achieve good agreement between the modeled and experimental data.   Zero-phase current transformer, power inverter, precision current transformer, magnetic amplifier.
