The testing of the exfoliation corrosion has shown neither change of a surface color (including any darkening) nor a corrode layer on surface or end faces of studied samples. Thus, according to GOST 9.904-82, the resistance of a given alloy to the exfoliation corrosion was evaluated with a grade “1”, which corresponds to no change of a sample surface. Moreover, a low average value of the corrosion rate about 0.006 mm/year (see Table 3) in comparison to conventional 5xxx and 6xxx alloys given in a work of Ahmad et al. were obtained.
