This paper presents the effect of Cadium in Aluminium alloys on mechanical property and phase transformation in the alloys. The Aluminium 4,8Cu 0,6Mn 0,2Ti alloys that contain between 0,150 and 0,288 Cadmium not only enhanced strength but also stabilized physical-mechanical properties. These characteristics are particularly shown on high temperature conditions. Although Cadmium does not participate in the resistance phases of the alloys, it still can maintain and dispose the vacancies in Al-Cu-Mn alloys after tempering. That's reason why Cadmium can control the precipitation of the resistance phase - CuAl2- in the tempering process.
