Tape, a circle, a wire 45H - alloy 45
The soft magnetic alloy precision 45H is a magnetic material having 19 according to GOST 693−74 induction coercive force is not more than 4 kA / m. It has a high initial permeability, it is magnetized to saturation in weak fields, thanks to the balanced composition. It has high magnetic permeability and saturation induction maintenance. It is used for the cores mezhdulampovyh, small power transformers, relays, chokes, components of magnetic circuits operated without bias or with a small magnetic bias at elevated induction.
Soft magnetic alloys are melted in special metallurgical furnaces with batch of high purity, after cooling is subjected to pull the shoes or rental. The group of soft magnetic materials belongs to a particularly pure ferromagnetic iron, low carbon electrical (unalloyed and siliceous) steel, low coercitive precision alloys Fe-based composite powder ferroalloys.
Production of transformers, electronic and electrical equipment, automation systems, telemetry, computer engineering. Production of cores microphones, transformers, components, electronic memory, magnetic circuits for use in sea water, and magnetic antenna components for electric machines. They are used in the field of innovative technologies, precision machine tools, household appliances, production of precision electronic devices, laser technology, for metrological equipment.
