【Abstract】 The influences of the contents of Sb and As in the lead base alloys on the corrosionweight loss and mechanical properties were studied. The grid alloy containing 3.5% antimonyand 0.15% As was scrcened for low maintenance lead acid batteries. The results indicatedthat the crystal structure and distribution of antimony in alloy were affected oviously by thbeaddition of As. The influence of Sb and As on the corrosion weight loss and mechanical pro-perties is discussed.更多还原
