Purpose: The aim of this investigation was to define optimum heat treatment parameters so as to received the alloy resistant for stress corrosion cracking, within the limits of the corrosion factor i.e. artificial sea water (3 % NaCl solution). Design/methodology/approach: The corrosion tests (in corrosion environment and inert-glycerol) were carried out on the device, making possibility extension of the samples with constant speed until break. Another investigations: SEM, tensile and Vickers hardness tests, X-ray Phase Analysis, light microscopy and TEM. Findings: The researches included structural analyze, mechanical and corrosion investigations, which allow to define the optimum parameters (quenching at 560ºC temperature, in water, artificial ageing at temperature160ºC/12h) so as to received the alloy resistant for stress corrosion cracking. Research limitations/implications: Contributes to research on corrosion protection for aluminium and its alloys. Practical implications: Conducted investigations lay out the areas of later researches, especially in the direction of the possible, next optimization tests of their structure, e.g. in the range of raising resistance on corrosion cracking in chosen media. Originality/value: The range of possible uses the regard also increases from this, as materials on working constructions in the investigated aggressive environment.
