| A LEAD ALLOY ANODE WITH IMPROVED RESISTANCE TO CORROSION IS PROVIDED FOR SULFATE ELECTROLYSIS WHICH ANODE CONSISTS ESSENTIALLY BY WEIGHT OF NOT MORE THAN 5% THALLIUM, NOT MORE THAN 1.8% TIN, UP TO 0.2% COBALT AND THE REMAINDER LEAD AND INCIDENTAL IMPURITIES. FURTHER IMPROVEMENT RESULT OF THE CAST ALLOY ANODE IS "HOT WORKED" BY ROLLING THE ANODE TO LESS THAN ONE-QUARTER ITS ORGINAL CAST THICKNESS WHILE MAINTAINING THE TEMPERATURE BETWEEN 200*-300*C.

| A CREEP RESISTANT, LEAD-BASED SOLDER PARTICULARLY USEFUL IN FABRICATING AUTOMOBILE RADIATORS IS DISCLOSED. IN A PREFERRED EMBODIMENT, THE SOLDER COMPRISES 2.5-5% TIN, 10-20% BISMUTH AND BALANCE LEAD. SOLDER OF THIS COMPOSITION WILL WITHSTAND A STRESS OF 400 P.S.I. AT 220*F FOR 50 HOURS OR MORE AND CAN BE HEAT TREATED TO WITHSTAND EVEN HIGHER STRESSES UNDER THE SAME CONDITIONS.
