摘要

"LEAD ALLOY FOR ACID LEAD ACCUMULATOR GRIDS, ACID LEAD ACCUMULATOR GRID, AND, ACID LEAD ACCUMULATOR". The invention relates to lead alloys for grades of lead acid accumulators comprising calcium, at a relative weight concentration between 0.05% and 0.12%, tin at a relative weight concentration below 3%, aluminum at a relative weight concentration between 0.002% and 0.04% and barium, the barium concentration being less than 0.02%.
