This study discusses the results of smelting of beverage cans poured into a tube mold, 5 cm in diameter and 30 cm high containing 6 ml, 12 ml of used lubricant, and without used lubricant as a comparison. Samples were treated with quench heat at 550 oC for 2 hours and aging at 175 oC for 1, 3, and 5 hours, respectively, to determine their effect on material hardness. From the analysis, it has been shown that the maximum aging time to increase the hardness of the material with and without the addition of used lubricant is 3 hours, then decreased after 5 hours. As well as the addition of used lubricants, the results show the hardness of aluminum material has decreased
