Lead alloys have been widely used in the hydrometallurgy domain owing to their excellent corrosion resistance and electrocatalytic performance.In the field of hydrometallurgy, the corrosion resistance of lead alloys with different microstructures plays an important role in the production cost as well as the quality of cathode products.Furthermore,the electrocatalytic performance of lead alloys is also related to their microstructure.Therefore, the corrosion resistance and electrocatalytic activity of lead alloys are two important reference indicators for evaluating their performance.Currently, strategies for improving the performance of lead alloys are divided into optimization of alloy composition and plastic processing deformation.In this paper, the effects of alloy optimization of alloy composition (mainly Pb-Ag alloy series and Pb-Ca-Sn alloy series) and rolling on the corrosion behavior and electrochemical behavior of lead alloys were briefly reviewed, and the corresponding prospects were made.
