ALUMINUM IN MARINE ENVIRONMENTS

ALUMINUM CORRODES BY PITTING IN MARINE ATMOSPHERES, BUT THE EXTENT OF THIS PITTING IS SO SLIGHT THAT IN TESTS OF THREE YEARS' DURATION NO APPRECIABLE LOSS IN STRENGTH OCCURRED. DEPTH OF PITTING WILL VARY CONSIDERABLY FROM PLACE TO PLACE, BUT WILL GENERALLY NOT EXCEED FOUR OR FIVE MILS TOTAL DEPTH IN TWENTY YEARS. THE MAXIMUM DEPTH OF ATTACK MAY REACH AS MUCH AS FOURTEEN MILS IN TWENTY YEARS UNDER ADVERSE CONDITIONS. FROM A STRENGTH STANDPOINT, THE DATA PRESENTED INDICATE THAT THE UNDERWATER CORROSION OF ALUMINUM IS SLIGHT AND CAUSES NO GREAT CHANGE IN THE MATERIAL.
