Abstract

PURPOSE: To offer a low-cost magnetic alloy composed of a single alloy based on Fe-Cr-Co, having a complex magnetic property, excellent in workability and abound in mass-producibility.
CONSTITUTION: The magnetic alloy comprises, by weight ratio, 17W35% Cr, 8W 20% Co, 0.1W8% of one or more of Ti, Zr and Hf, and the balance being Fe. The alloy may contain 0.1W10% of one or more of Mn, Y, Cu, Zn, Al, C, R.E., Ru, Rh, Pd, Os, Ir and Pt as additional components. The alloy can be provided with a desired complex magnetic property by subjecting it to special heat treatment and working. That is complex magnetic property is obtained by solution-treating the alloy in an α-γ dual phase zone and utilizing the spinodal decomposition of each phase, a γ→α' transition mechanism and an age-precipitation-hardening mechanism so that mainly α contributes to a large coercive force while γ contributes to a small coercive force.
