This paper presents the results of heat treatment influence, including quenching in water, cooling of the alloy in liquid nitrogen, holding in it and thermal shock (heating in hot mineral oil) and also natural or artificial aging on the properties of wrought aluminum alloy D16 (2024). With the help of the hole-drilling strain-gage method the influence of heat treatment on residual stresses was determined and using tensile and indentation tests – specific elongation, reduction of area, yield strength, tensile strength and cracking resistance of alloy D16 (2024) were determined. Corrosion properties were studied with potentiodynamic method in 3% aqueous NaCl solution.
