Abstract

Modern low-coercivity thermomagnetic materials used in the electrical engineering, electronics, and tool engineering are reviewed. They are primarily for the manufacture of magnetic shunts, magnetic secondary resistance, and heat-sensitive elements to a relay, whose actuation is determined by the temperature near the Curie point). The effect of the alloying additives (Mo, Cr, Cu) on the magnetic properties, heat treatment, and the properties of structural changes in iron–nickel alloys is considered. The advantages of new thermomagnetic powder materials in comparison with cast alloys are demonstrated. Also, the prospects of their application in electrical engineering are considered.
