Chassis is a frame that functions as a support for vehicles, engines and passengers weight. The chassis also serves to hold the vehicle to remain rigid and not experience bending. To meet the needs of the global market for chassis products with good material quality, of course it can not be separated from how the product is made, starting from the casting process, heating to the final process (finishing). In this research, the chassis was made with aluminum waste material which is mixed with copper (Cu) and mixed with Magnesium (Mg) through the casting process. This research was carried out with Al and Cu alloys, Al and Mg and it was carried out by tensile and bending, hardnest tests. Aluminum is melted at the melting point and added with Cu powder ang with Mg powder with a composition of 0%, 1%, 2%, 2,5% and 3%. Alloy results are printed according to the tensile, bending and hardnest material test standards. Based on the results of tensile, bending and hardnest tests it can be concluded that the composition of 2% is the lowest elasticity alloy and 3% is the highest elasticity alloy.
