Abstract
The present invention relates to an amorphous metal alloys of the formula: Cr.sub.a X.sub.b M.sub.c wherein X is at least one element selected from the group consisting of Pt, Pd, Ir, Rh and Ru; M is at least one element selected from the group consisting of P, B, N, C, As, Sb and S; and wherein a ranges from about 0.60 to abotu 0.96; b ranges from greater than zero to about 0.01; c ranges from about 0.04 to about 0.40; and with the provisor that a+b+c equals 1.00.
