Abstract
A semi-hard magnetic alloy is described which consists of, by weight, 15-50% Co, 5-25% Ni, 1-9% Cr, balance Fe and incidental impurities and containing further a positive amount of up to 10% Cu or Ti. The alloy is characterized by exhibiting composite hysteresis characteristics as shown in FIG. 3 of the drawings. The alloy may be produced by a repetitive cold-working and subsequent annealing steps, the annealing step being carried out at temperatures of between 450.degree. and 750.degree. C.
