Abstract
A process is provided for increasing the strength of antimony-lead alloys by specially treating an alloy which contains an effective amount of arsenic in the alloy, the process comprising working the alloy, rapidly heat treating the alloy, which includes quenching, for a period of time sufficient to activate a strengthening mechanism in the alloy. The process is especially useful for the manufacture of battery grids on a continuous production line.
