Feature

Precision alloy brand 80NKHS relates to soft magnetic materials. Has a small coercive force and very high magnetic permeability at induction of saturation of 0.65−0.75 T in weak fields. After heat treatment with slow cooling starting from +600°C becomes the minimum deviation of characteristics in the climatic temperature range. Used for cores compact transformers, relays and chokes, working in weak magnetic fields, screens; the manufacture of non-contact relays of small thickness (less than 0,02 mm) magnetic amplifiers and pulse transformer cores. The alloy has high value of initial magnetic permeability, can be magnetized to saturation in weak fields, by the addition of cobalt and Nickel.

Application

Soft magnetic alloy brand 80NKHS successfully applied to magnetic cores of the magnetic alternating field. Finds wide application in modern instrumentation in the manufacture of microphones, the cores of transformers, components, computer memory, magnetic circuits for operation in sea water, magnetic antennas. Used in transformer industry, electrical engineering, electronic and electrical industry, the systems of automatics and telemechanics, measurement and computing.

Production

Soft magnetic materials are produced from low-carbon steels based on high purity ferromagnetic iron, electrical nizkobonitetnyh alloys on iron or iron-based powder and composite ferromagnets. Such special alloys melted in induction furnaces, after which the ingots are subjected to Rankovce or rental.
