Herein, the study of a multicomponent alloy comprising Fe, Co, Ni, Ga, and Nb is presented. The study begins with analysis of small samples, and these samples results conducted to the production of a laminated alloy with composition FeCoNi(GaNb)_0.20, which has its magnetostriction roundly determined. This alloy is found to have longitudinal magnetostriction of less than 5 ppm. In addition, the material shows high values of initial and maximum relative permeabilities of 1160 and 1340, respectively. The saturation magnetization of the alloy is 97.4 Am² kg⁻¹, and the electrical resistivity is 88 μΩ cm. Moreover, it is demonstrated that this alloy has good mechanical workability. Overall, the studied FeCoNi(GaNb)_0.20 alloy has potential to be used in electric machines and magnetic devices that work in the subkilohertz frequency range.
