Abstract
Abstract: Aluminum alloy was used widely in the industrial world because it has a variety of advantages. This research was conducted to find out the influence of the silicon contents on the remelted motorcycles rim. The silicon contents of 2%, 4%, 6%, and 8% were added to the sand casting. The specimens were characterized by using as an optical microscope, brinell hardness tester, and universal testing machine. The highest tensile strength obtained on the specimen with the silicon of 6% (144,66 N/mm2). The highest hardness was obtained on the specimen with the silicon of 8% (67,18 BHN). Optical micrograph investigation showed that the phase changes of hypoeutectic, eutectic, and hypereutectic along with the addition of Si in Al-Si alloys. Key Words : Aluminium alloy, Sand Casting, Tensile strength, Hardness, Microstucture.
