49KF mark relates to a precision alloy soft magnetic alloys and magnetic saturation is not less than 2.35 T, a high Curie point of 950 ° C and high magnetostriction. Soft magnetic materials have high initial magnetic permeability value can be magnetized to saturation in weak fields. These include such alloys, whose composition includes in addition to iron cobalt and nickel.
The group of soft magnetic materials are very pure ferromagnetic iron, low carbon electrical (doped and silica), low coercitive precision steel alloys Fe-based powder composite ferroalloys. Smelted in special metallurgical furnaces. The cast ingots are subjected to pull the shoes or rental.
The magnetic cores of transformers, microphones, pole pieces solenoids. Radio engineering and electrical innovative equipment, automation and remote control systems, measuring, computing equipment. Production of electronic memory components, magnetic circuits for use in seawater, magnetic antennas. Production of precision electronic devices, household appliances, lasers, metrology equipment.
