Abstract
The corrosion behavior and its main influencing factors of two Al-alloys in sea environment were analyzed by salt water dip test,electrochemical test and microstructure measurement.The results showed that in 3% NaCl solution,pitting corrosion generated in alloy 1413 because it has more second phases containing Fe,Si,general corrosion occured in alloy 5056 which has little second phases.
