Abstract Al-Mg alloys are considered as the ideal electromagnetic shielding materials and widely applied on electronic and communication servicing in marine environment due to their excellent comprehensive properties, such as high specific strength, low electric resistivity and excellent corrosion resistance. The microstructure and corrosion behavior of Al-3.0%Mg-0.12%RE alloy wires subjected to different cold drawing deformation was investigated by means of optical microscope (OM), scanning electron microscope (SEM), energy disperse spectroscopy (EDS) and electrochemical measurement. The influence of cold-drawing strain and microstructure on corrosion resistance of the alloy was also examined. The results indicated that the equiaxed grains of the alloys were elongated and the skeletal second phase particles were fragmented during the cold-drawing process. The corrosion behavior of the Al-3.0%Mg-0.12%RE alloy showed typical characteristics of pitting corrosion at the position of second phases. With the increase of strain, the uniform corrosion sensibility increased, pitting corrosion sensibility declined and the corrosion resistance of the alloy improved.
