Abstract
Making aluminum product use recycling beverage aluminum cans can reduce the cost of metal production compared to the primary process that starts from the smelting process. One of the manufacturing methods used to recycle aluminum waste is the casting process. Usually, the problem with castings is that they are not homogeneous in the as-cast due to segregation. So that in this study a homogenization process on recycling aluminum castings will be carried out to obtain more homogeneous mechanical properties and microstructure. Variables that influence are heating temperature and holding time during the homogenization process. In this research, the heating temperature used ranges from 500 C to 600 C, and the holding time used is 2 to 4 hours. The optimum condition in this study will obtain if mechanical properties, such as tensile strength and hardness, uniform at any castings location
