RESISTANCE OF ALUMINUM-BASE ALLOYS TO 20-YEAR ATMOSPHERIC EXPOSURE

THE PERTINENT DATA OBTAINED ON WROUGHT ALUMINUM-BASE ALLOYS AFTER ATMOSPHERIC WEATHERING EXPOSURE PERIODS OF 1, 3, 6, 10 AND 20 YEARS HAVE BEEN TABULATED AND ALSO ARRANGED GRAPHICALLY TO ILLUSTRATE CHARACTERISTICS OF SPECIFIC INTEREST, SUCH AS (1) EFFECT OF NATURAL AGING ON THE TENSILE STRENGTH OF SPECIMENS STORED INDOORS FOR 20 YEARS, (2) RATING OF THE CORROSIVITY OF THE SEVEN ATMOSPHERIC CONDITIONS EMPLOYED, AND (3) THE RATE OF WEATHERING OF THE FIVE ALUMINUM ALLOYS. THESE IMPORTANT DATA HAVE BEEN FURTHER ENHANCED BY CORRELATING THEM WITH EQUALLY LONG-TIME DATA OBTAINED BY THE ALUMINUM RESEARCH LABORATORIES ON SIMILAR ALLOYS IN OTHER ATMOSPHERIC ENVIRONMENTS, AND ON NEWER ALUMINUM ALLOYS WHICH NOW COMPLEMENT OR SUPERSEDE THE ALLOYS WHICH HAD BEEN IN THE ASTM INVESTIGATION. /AUTHOR/
