摘要
A lead acid battery grid made from a lead based alloy containing calcium, tin, and silver having the following composition: calcium above 0.06 and below 0.082%, tin above 1.0% and below 1.2%, silver between 0.005 and 0.020%, and optionally containing up to 0.025% aluminum. To enhance corrosion resistance and reduce grid growth, the grid optimally may contain 0.005 to 0.05% copper as an alloying element complementary to and as a replacement for part of the silver, provided the silver content does not fall below 0.005% and no more than a trace of aluminum is present.
