Alumunium material widely used in the automotive industry sector such as vehicle pistons and it's increasing every year. The impact of this used resulted the increasing in the waste of used aluminum materials that are inorganic. One of the abundant aluminum waste materials was vehicle pistons which have tough properties with relatively high durability. Used piston components can be reused as other components through the remelting process. This study aims to identify changes in the chemical composition of pistons and the former pistons and to analyze the mechanical properties of remelting pistons using both molds. After the melting process and removing the slag, the used aluminum piston liquid metal is poured into sand molds and steel molds, then the chemical composition is tested using a spectrometer, mechanical hardness testing with micro vickers, and phase analysis by metallographic observation. The results of this study indicate that the chemical composition results are not much different between the piston before being melted with the remelting piston in the sand mold and the steel mold. While in the hardness test, there are differences in the piston before being melted with the remelting piston in the sand mold and steel mold due to the phase difference in the metallographic analysis due to the different cooling processes between the sand mold and the steel mold. The hardness value of piston remelting products using steel molds is greater than using sand molds, respectively 118.03 HV for steel molds and 83.95 HV for sand molds. [ABSTRACT FROM AUTHOR] |
