46--50

This article presents the process of extrusion shape of complex geometry cross-sectional 7039 aluminum alloy for use in aerospace industry. This study aims to characterize the properties of aluminum alloy as structural material and to determine the technological parameters of the indirect extrusion press and their influence on mechanical properties and the microstructure of the final product. It has been proved that the proper choice of parameters in the case of a specific profile extruded from 7039 aluminum alloy allows the manufacturing of products of complex cross-sections and the quality required in aerospace industry.
