Aluminium alloys of the 7xxx series, due to their low density and high strength, play a significant role in the aerospace and transportation industries. This study focuses on the aluminium alloy 7075, whose mechanical properties were further enhanced through precipitation hardening. Ageing was conducted at three different temperatures (105 $^°$C, 120 $^°$C and 140 $^°$) and for various durations. The effects of the heat treatment were evaluated based on changes in hardness, electrical conductivity and corrosion resistance. Finally, the precipitated phases in the microstructure were characterised through metallographic examination using an optical light microscope.
