Abstract

The process of melting the metal by melting, then poured into the mold and allowed to freeze. The metal will undergo phase change during the casting process, caused by the clotting process, this change in properties among others depends on the cooling medium used during the cooling process. Because a metal is very important in a machining construction, in this study used different cooling fluid oil viscosity that is : SAE 40 oil, SAE 90 oil, SAE 140 oil. The purpose of this study was to examine the effect of red sand mold on chemical composition mixture, hardness, microstructure in cast aluminium products with oil cooling. From the test of hardness of speciment with SAE 140 oil media has better hardness value compared to SAE 40 oil and SAE 90 oil. From the test of chemical composition there are 17 elements, but only 5 elements that most influence on aluminium cast are Si, Fe, Cu, Mn, and Zn are the most dominant.
