Aluminum has a wide range of commercial applications due to its good corrosion resistance, light weight, good mechanical properties and ease of fabrication. Aluminum-Silicon alloy has good cast and weld ability, good thermal conductivity and excellent corrosion resistance. As the times progress, the industrial world is currently required to improve the quality of its products. The purpose of this study was to determine the mechanical properties of Al-Si alloy after adding other materials. The strengthening method for Al-Si alloy uses the stir casting method. The result was that the addition of Fe2O3 undoped and doping graphene could not increase the tensile strength of the Al-Si alloy and conversely the addition of Fe2O3 undoped and doped graphene decreased the tensile strength of the Al-Si alloy. The addition of Fe2O3 undoping graphene and Fe2O3 doped graphene materials to the Al-Si alloy had an effect on the hardness of the Al-Si alloy, namely an increase in the hardness value of raw Al-Si 108.83 HV after adding Fe2O3 material undoping graphene to 111 HV and to 134.83 HV after adding graphene doped Fe2O3 material.
