Amorphous alloys comprising 30 to 75 atomic % Cr, the remainder being substantially at least one element selected from the group consisting of Ti and Zr and alloys represented by the general formula: XaCrbMc wherein X is at least one element selected from the group consisting of Ti and Zr; M is at least one element selected from the group consisting of Mg, Al, Fe, Co, Ni, Cu, Mo and W; and a, b, and c are, in atomic percentage, a > 20, 20 b 75, 0 < c 20 and a+b+c = 100. The alloys are excellent in corrosion resistance and wear resistance, form a stable protective film and are spontaneously passive, even in corrosive environment such as a poorly oxidizing, highly corrosive HCl solution and solutions containing chlorine ions.
