| Abstract: | The Tensile Properties of A357 casting aluminum alloy are investigated at room temperature and 150℃ high temperature. The experimental results show that the mechanical properties of A357-T5 casting aluminum alloy are slightly better than that of A357-T6 casting aluminum alloy at room temperature, while at 150℃ high temperature, the mechanical properties of A357-T6 casting aluminum alloy are better than that of A357-T5 casting aluminum alloy. The cast defects are porosties, or inclusions of Al2O3 or SiO2. |
