Abstract

The metal will undergo phase change during the casting process, both physical and mechanical changes caused by the clotting process. Changes in this character are among others influenced by the cooling medium used during the cooling process due to the physical and mechanical properties of a metal is essential in the construction of machinery. So in this research used different cooling media that is: Water with temperature 15 ° C, Water with temperature 27 ° C and Water with temperature 55 ° C. The purpose of this study was to compare the physical and mechanical properties of aluminum casting with different cooling media. From testing hardness of specimen with water cooling medium 15 ° C has better hardness value than water with temperature 27 ° C and 55 ° C. From the test results of chemical composition there are 17 elements, but only the 4 most influential elements on cast aluminum are Si, Fe, Cu, and Zn the most dominant. Viewed from the elements present in this material can be classified metal aluminum zinc alloy (Al-Zn).
