ABSTRACT
Aluminium is widely used in everyday applications, including beverage cans and automotive components. The increasing use of aluminium correlates with increasing amounts of waste if not managed properly. Metal casting is one solution for waste processing. The pouring temperature in metal casting greatly influences the final result. This research aims to investigate the impact of casting temperature on the tensile strength and microstructure of Al-Mg alloy used beverage cans using the lost foam casting method for bell stands using casting temperature parameters of 650 °C, 700 °C and 750 °C. The pattern is made using styrofoam material which is cut using hot wire and placed in a sand mold with a mesh size of 40. The molten metal is poured into the mould cavity using a split channel system with risers. The results of the research show that the tensile strength decreases with increasing casting temperature due to the trapping of hydrogen gas. The tensile strength at a casting temperature of 650 ℃ to 700 ℃ decreased by 14% from 129.25 MPa and at a casting temperature of 700 ℃ to 750 ℃ it decreased by 26.01% from 111.15 MPa. Microstructure observations show that the area of the α phase increases with increasing pouring temperature. The area of the α phase at a pouring temperature of 650 °C to 700 °C increased by 1.21% from 265,476.10 μm2 and at a pouring temperature of 700 ℃ to 750 ℃ increased by 5.38% from 272,366.59 μm2. The area of the α + β-Al3Mg2 phase decreases with increasing casting temperature. The pouring temperature of 650 °C to 700 °C decreased by 16.51% and the pouring temperature of 700 ℃ to 750 ℃ decreased by 42.08%. These results can be a reference for the metal casting industry in selecting casting temperatures in Lost Foam Casting foundries.
