Abstract
The effects of chemical composition and cooling rate on the mechanical properties of Pb–Sb–Sn–As grid alloys for lead-acid batteries were investigated. Mechanical properties were characterized in terms of ultimate tensile strength and elongation at room temperature. Composition and cooling rate of the studied alloys should ensure the increase in the amount of Sn soluble in α-Pb and the decrease in the amount of brittle arsenic precipitates or eutectic β-Sb phase in the structure.
