Heat treatment of aluminum alloys is performed mainly to increase mechanical properties of the alloys. Very important issue, from improvement of mechanical properties point of view as well as economical aspects of performed treatment, is selection of a suitable parameters of solutioning and ageing operations. The paper presents results of the investigations concerning effect of the performed heat treatment on change of tensile strength of the EN AC-46000 (AlSi9Cu3) alloy. Investigated alloy was melted in electric resistance furnace. Run of crystallization is presented with making use of the thermal derivative method (ATD). This method was also implemented to determination of heat treatments’ temperature range of the alloy. Performed heat treatment resulted in growth of the R_m tensile strength. Performed tests have enabled determination of temperature and duration of solutioning and ageing operations of the investigated alloy, which would condition obtainment of improved R_m tensile strength. The tests were performed in laboratory conditions.
