The paper provides the information of corrosion - fatigue characteristics of aluminium alloy 4043 (AA4043). Casted
aluminium alloy 4043 was used for tensile and fatigue test with and without corrosion. The ultimate tensile strength obtained
from tensile test and was used to conduct fatigue test on rotating bending fatigue testing machine as per RR Moore rotating
bending fatigue test for un-corroded specimens for different stress values and compared the results with that of corroded
specimens. The S-N curves were plotted. It is found that the corroded specimen became weak due to formation of oxides on its
surface which resulted in early failure
