    Abstract

    Aluminum Matrix Composites (AMCs) is one kind of advanced materials that are being developed today. AMC is widely used in applications that require high performance, such as the machining of aircraft, or also in the automotive industry This research aims to determine the effect of Mg to improve wettability on aluminum matrix composite piston remelting reinforcement SiO2 using stir casting method to the value of hardness and density. The stirring process temperature is 650oC, with a stirring speed is 600 rpm for 5 minutes, and the pouring temperature is 725oC, and the variations of mass Mg fraction are 1%, 1.5%, 2%, and 2.5% with size fraction mass of 9% SiO2 using mesh 270. The Brinell hardness testing using the standard ASTM E-10, and the density testing using Archimedes method. The results showed that the addition of a mass fraction of magnesium (Mg) 2% has the highest hardness is 88.433 HBN, This behavior indicates that the addition of magnesium (Mg) to increase the density and reached a high value is 2.68 g / cm3 in the variation of the addition a mass fraction of magnesium (Mg) 2.5%. Keywords: Aluminium, Piston, Stir Casting SiO2, Mg, Wettability, Brinell Hardness, Density
