A process for strengthening a lead-antimony alloy which alloy significantly retains its physical properties after mechanical working, the alloy comprising, by weight, about 0.5%-6% antimony, about 0.002%-1% arsenic, about 0.0005% to 1% tellurium, the balance essentially lead, comprising: (a) working the alloy by rolling to produce a structure containing soluble antimony in the form of antimony-rich eutectic phase bands; (b) heating the alloy at an elevated-temperature for a sufficient time to provide an alloy having a recrystallized structure which strengthens on aging and which structure contains greater than 50% of the soluble antimony in the antimony-rich eutectic phase bands and less than 50% of the soluble antimony being dissolved in the lead; and (c) quenching the alloy. |
