A new series of glassy metal alloys with near-zero magnetostriction is disclosed. The glassy alloys have the composition (Co. sub.x Fe.sub.1.sub.- x).sub.a B.sub.b C.sub.c, where x ranges from about 0.84 to 1.0, a ranges from about 78 to 85 atom percent, b ranges from about 10 to 22 atom percent and c ranges from 0 to 12 atom percent, with the proviso that the sum of b and c ranges from about 15 to 22 atom percent. The magnetostriction of these alloys ranges from about +5 × 10.sup.-. sup.6 to -5 × 10.sup.-.sup.6 and the saturation induction is at least about 10 kGauss. The transition metal content is responsible for the low magnetostriction in these alloys, as well as their high saturation induction. The metalloid content (needed to stabilize the glassy state which is one of low anisotropy) strongly affects the saturation induction and Curie temperature, but not the magnetostriction.
