摘要： AN ALUMINUM CASTING ALLOY HAVING GOOD MECHANICAL PROPERTIES IS PREPARED BY ADDING, TO ALUMINUM, COPPER, MAGNESIUM, AND CADMIUM AND, ADDITIONALLY, IF DESIRED, TITANIUM AND BORON, AND, ADDITIONALLY. IF DESIRED, MANGANESE AND SILVER, SOLUTION-HEAT-TREATING THEREOF AT A TEMPERATURE HIGHER THAN 500*C., AND THEN AGEING THE SOLUTION-HEAT-TREATED ALLOY AT A TEMPERATURE BETWEEN 160*C. AND 190*C. FOR 4 TO 48 HOURS. THE ALLOY IS USEFUL IN VARIOUS TYPES OF MACHINE MEMBERS, AIRCRAFT, ROLLING-STOCK MEMBERS, ARCHITECTURAL MEMBERS, AND OTHER STRUCTURAL APPLIANCES.

摘要： 1. THE METHOD OF MANUFACTURING A HIGH STRENGTH ALUMINUM ALLOY FOR ELECTRIC CONDUCTORS COMPRISING THE STEPS OF PRODUCING A HEATED ALLOY WHICH COMPRISES 0.2 TO 1.2 WT.-PERCENT MAGNESIUM, 0.1 TO 0.9 WT.-PERCENT SILICON, 0.0005 TO 0.4 WT.-PERCENT BERYLLIUM AND THE BALANCE ESSENTIALLY ALUMINUM; COLD WORKING THE PRODUCED ALLOY WITHAPPROXIMATELY 10 TO 30% REDUCTION IN AREA AFTER QUENCHING THE HEATED ALLOY FROM IN THE RANGE OF ABOUT TO 550* C.; THEN AGING THE ALLOY AT ABOUT 150* C. TO 200* C.; AND THEN COLD WORKING THE ALLOY.
