ABSTRACT The effect of ageing temperature on the mechanical properties of Al-Mg-Si alloy has been
studied. The material was machined into different shapes of the tests to be carried out: tensile,
impact and hardness. The test specimens were divided into two and, some sets were solution
treated at 500℃ for one hour and peak aged at 160℃ for eight hours while the other sets were
solution treated at 500℃ for one hour and peak aged at 180℃ for eight hours. The abovementioned
tests were carried out on the specimens. The results show that at low ageing
temperature of 160℃, the ductility and impact were high while at 180℃, the ultimate tensile
strength and hardness are higher compared to the value obtained at 160℃.
