Abstract:

Aluminum alloy X2020-T6 sheet 0.064 inch thick was tested at room temperature, 300, 400, and 500 F after 12, 10 and 100 hours and at room temperature after the several elevated temperature exposures to determine mechanical properties of design interest. The room temperature and elevated temperature properties found after 100 hours exposure to the various temperatures are tabulated to indicate the trends occasioned by temperature increases. Room temperature properties found after heating are also tabulated to indicate strength and ductility reductions occasioned by heating. Salt spray exposures of 250 hours were applied to material heated at 300, 400, and 500 F for 100 hours, and as a result no significant strength reductions resulted however, the ductility was severely reduced by salt spray corrosion by 18 to 53 of the initial value.
