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.
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 size, low loss at high frequency, time, and have good stability and function of special electronic components.In communications, instrumentation, electronic computer, remote sensing, remote control, etc are widely used in the system.
