Abstract Scope This study investigates how cold forging (plastic deformation) influences the mechanical properties of high-magnesium ECO-Almag alloys. The experiments were strategically designed to control the deformation level through specific die and workpiece geometries, systematically varying two key parameters: the Mg concentration and the forging ratio.The mechanical response was evaluated via tensile tests, with quantitative analysis focusing on the work hardening effect. Changes in yield strength ($\sigma_y$) and ultimate tensile strength (UTS) were examined as a function of the forging ratio for each Mg level. By comparing these results to the characteristics of the unforged raw materials, this research provides essential data on the strengthening behavior induced by the forging process. Furthermore, the improvement in properties was compared with results from prior studies on 5xxx series aluminum alloys using a diagram that illustrates the paradox of strength and ductility.
