In order to analyze the influence of spalling corrosion on mechanical property of 6005A aluminum alloy,test on 6005A aluminum alloy plate was carried out,and the mechanical property was tested to obtain the degradation rate and degree of mechanical property at different corrosion times.The result shows that the mechanical property of 6005A aluminum alloy plate decreases with the extension of corrosion time,and the corroded 6005A aluminum alloy plate will have microcrack along grain and corrosion gap,resulting in stress concentration under tensile stress,and the reduction of mechanical property.
