ABSTRACT:
An alkali metal containing low antimonial content lead alloy characterized by improved ductility for use as an electric storage battery grid or in acidic environments suitably contains from 0.5% to 3.0% Sb, 0.01% to 0.7% As, 0.001% to 0.7% Sn, 0.001% to 0.15% Cu, 0.001% to 0.015% S or 0.001% to 0.05% Se or admixtures thereof and 0.001% to 0.05% of an alkali metal. Battery grids made from the alloy are resistant to electrochemical corrosion, gassing, and grid growth as well as exhibiting improved bend ductility.
