Abstract

The metal will undergo phase change during the casting process, either the physical or mechanical changes caused by the freezing process. This change in properties is influenced by the cooling medium used during the cooling process. Because the physical and mechanical properties of a metal are very important in machining construction, in this study used different cooling media, namely: air room temperature, well water and SAE40 oil. The purpose of this research is to compare the physical and mechanical properties of aluminum casting with different cooling media. From the hardness testing of the specimen to the well water well refrigerant medium has a better hardness value compared to the room temperature and SAE40 oil. From the results of testing the chemical composition there are 17 elements, but only the 4 most influential elements in the cast aluminum Si, Fe, Cu, and Zn the most dominant. Judging from the elements present in this material can be classified metal aluminum zinc alloy (Al-Zn).
