A lead-containing lead alloy for the manufacture of lead acid battery grids and conductive parts. Compared with pure lead, the melting point is lower, the fluidity in the molten state is good, the casting is easy to form, and the hardness after solidification is large; the disadvantage is that the gas deposition super-potential of the grid is low. In order to reduce the precipitation of gas during charging of the battery, reduce self-discharge and improve corrosion resistance, the amount of strontium has been gradually reduced from the conventional 5% to 7% to about 2% or even lower. A small amount of other ingredients such as tin, arsenic, sulfur, selenium and copper are also selectively added to improve the physical and chemical properties of the alloy.
