Lead-antimony alloys design

FMl. Positive-plate expansion. The use of lead-antimony alloy enhances the creep strength of the positive grid and thus retards growth in the plane of the plate. For the flat design of positive plate, expansion normal to the plate can be moderated by applying a compressive force to the plate group. Tubular positive plates have gauntlets that constrain the active material and reduce its tendency to expand, disconnect, and shed.
