1j50 permalloy Wire 500 Curie Point Soft Magnetic alloy High Magnetic Permeability permalloy

Soft magnetic iron nickel alloy is in iron nickel base with different number of Co, Cr, Cu, Mo, V, Ti, Al, Nb, Mn, Si and other elements of alloy, is the most versatile of iron nickel alloy, a kind of most varieties and specifications, dosage after silicon steel sheet and electrical pure iron.Compared with other soft magnetic alloy, the alloy in geomagnetic field has the very high magnetic permeability and low coercive force, some alloy also have rectangular hysteresis loop, or very low residual magnetic induction intensity and constant magnetic permeability characteristics and has a special purpose.

This kind of alloy has good anti-rust properties and processing properties, shape and size can be made very precision components.Because the resistivity of the alloy is higher than pure iron and silicon steel sheet, and easily processed into thin belt, so that under a few microns thin belt, apply to a few MHZ at high frequency.
Saturated magnetic induction intensity and Curie temperature of the alloy is higher than ferrite soft magnetic materials, in the aerospace industry and other electronic industry to produce high sensitivity, size precision, small volume, low loss at high frequency, time and temperature stability and function of special electronic components.In communications, instrumentation, electronic computer, remote control, remote sensing and so on are widely used in the system.

Soft magnetic alloy are in weak magnetic field with high permeability and low coercive force of alloys.This kind of alloy are widely used in radio electronics, precision instruments and meters, remote control and automatic control system, the combination is mainly used for energy conversion and information processing, the two aspects of is an important material in the national economy.

Introduction to the

Soft magnetic alloy outer magnetic field under the action of easy magnetization, basic disappear after removal of magnetic field of magnetic induction intensity and magnetic alloys.

The hysteresis loop area is small and narrow, coercive force generally below 800 a/m, high resistivity, eddy current loss is small, high permeability, high saturation magnetic induction.Are generally processed into sheets and strip.Melt was prepared.Mainly used for electrical appliances, telecommunications industry in various core components (such as transformer core, relay iron core, choke coil, etc.).Commonly used soft magnetic alloy has a low carbon electrical steel, eminem iron, silicon steel sheet, soft magnetic alloy, iron, cobalt soft magnetic alloy, nickel iron iron silicon soft magnetic alloy, etc.

Physical properties
Under the action of outside magnetic field easily after magnetization, except to the magnetic field of magnetic induction intensity (magnetic induction) and basic disappearance of magnetic alloy.Hysteresis loop area is small and narrow, coercive force (Hc) average less than 10 Oe (see precision alloy).In the late 19th century made of low carbon steel motor and transformer core.1900 magnetic higher silicon steel sheet quickly replaced the low-carbon steel, used in the manufacture of electric power industry products.In 1917 the Ni - Fe alloy to adapt to the current needs of the telephone system.Then the Fe - Co alloy with different magnetic properties (1929), Fe - Si - Al alloy (1936) and Fe - Al alloy (1950) to meet the special purpose.In 1953 China began production of hot rolled silicon steel sheet.The late '50 s and began to study Ni - Fe and soft magnetic alloy such as Fe, Co, 60 s gradually began to produce some of the major soft magnetic alloy.In the 70 s production of cold rolled silicon steel belt.

The magnetic properties of soft magnetic alloy mainly is: (1) coercive force (Hc) and low hysteresis losses (Wh);(2) resistivity (rho) is higher, low eddy current loss (We);(3) initial permeability (mu 0) and the maximum high

The main kinds of
Can be divided into low carbon electrical steel and eminem iron, silicon steel sheet, nickel iron soft magnetic alloy, iron, cobalt soft magnetic alloy, iron, silicon aluminum soft magnetic alloy, etc., in terms of electric power industry, mainly used in high magnetic field with high magnetic induction and low core loss of the alloy.In the electronic industry, mainly used in low or medium under magnetic field with high permeability and low coercivity of the alloy.Under high frequency must adopt the thin strip or higher resistivity of the alloy.Commonly used sheet or strip.

Soft magnetic iron nickel alloy
USES: most used in weak magnetic or secondary magnetic field work of small transformer, pulse transformer, relays, transformers, magnetic amplifier, electromagnetic clutch, the reactor core and magnetic shielding.
