At the beginning of the production of body parts from Al-alloy, there was a requirement to experimentally verify its suitability for their production. This alloy is characterized by a combination of various stress-deformation properties influencing the non-uniform plastic flow of the material, especially during deep drawing of complex shaped drawn parts. The properties evaluation of the analyzed material was focused on the experimental determination and comparison of the parameters with the parameters given by the producer. The experiments were supplemented by deep drawing tests of the drawn part under laboratory conditions. The magnitudes and courses of tensile and holding forces on the experimental tool and the magnitudes of deformations at individual drawn part points were evaluated. The experiments confirmed the suitability of the material for deep drawing. They also indicated the sensitivity of the material to the setting of process parameters - holding force and lubrication on the forming tool.Keywords: Car framework, Al-alloy, stress-strain characteristics, formability, testing methods
