Magnetically soft precision alloy 50NHS serves for cores of pulse transformers operating without submagnetization, stuffing of audio and high-frequency communication equipment. Characterized by a good initial magnetic permeability due to the presence of cobalt in the composition, magnetizes to saturation in weak fields. Such alloys with good magnetic permeability and minimal coercive force are indispensable in the manufacture of transformers, radio and electrical equipment, automation and telemechanics systems for computer and measuring equipment.


Magnetic-soft materials are produced from low-carbon steels based on ferromagnetic iron of special purity, electrotechnical low-coercive alloys on iron or iron-nickel base, powder and composite ferromagnetics. These alloys are melted in special induction furnaces after which the ingots are forged or rolled. The hardness of the 50NHS alloy is HB 10-1 = 125 - 190 MPa.


Production of transformers, computer memory components, microphone cores, magnetic cores for marine environments, magnetic antennas. It is used in the sphere of innovational technologies, precision machine tool building, for production of precise electronic devices, household appliances, laser optics, in products of measuring metrology equipment.
