Abstract

The present invention provides a high strength and anti-corrosive aluminum-based alloy essentially consisting of an amorphous structure or a multiphase amorphous/fine crystalline structure, which is represented by the general formula Al.sub.x M.sub.y R.sub.z. In this formula, M represents at least one metal element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Cu, Zr, Nb, Mo and Ni, and R represents at least one element or mixture selected from the group consisting of Y, Ce, La, Nd and Mm (misch metal). Additionally, in the formula, x, y and z represent the composition ratio, and are atomic percentages satisfying the relationships of x+y+z=100, 64.5.ltoreq.x.ltoreq.95, 5.ltoreq.y.ltoreq.35, and 0<z.ltoreq.0.4.
