Patent number: 5306363
Abstract: An aluminum-based alloy foil or thin aluminum-based alloy wire is produced from an amorphous material made by a quenching and solidifying process and having a composition represented by the general formula:Al.sub.a M.sub.b X.sub.cwherein M is one or more elements selected from a group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, Zr, Ti, Mo, W, Ca, Li, Mg and Si; X is one or more elements selected from a group consisting of Y, Nb, Hf, Ta, La, Ce, Sm, Nd and Mm (misch metal); and a, b, and c are atomic percentages falling within the following range:50.ltoreq.a.ltoreq.950.5.ltoreq.b.ltoreq.35 and0.5.ltoreq.c.ltoreq.25Such foil or wire has a smooth surface and a very small and uniform foil thickness or wire diameter, contains at least 50% by volume of an amorphous phase, and has excellent strength and resistance to corrosion. The foil thickness and wire diameter are reduced in a rolling or drawing process at an elevated temperature over a short time period.
