Mechanical characteristics of Al-Si alloys can be optimized for the specific application depending on the demands in various engineering sectors by the combinations of relevant material constituents and processing parameters. In recent years, many manufacturing techniques have been proposed, among them, the centrifugal casting technique is one of the most attractive methods for producing cylindrical component of Al-Si alloys with higher density. In this paper, Al-10wt%Si, Al-20wt%Si, and Al-30wt%Si alloy were cast by varying mold rotational speeds. In this method, mold rotational speed and fluid flow play a major role, and understanding the flow process is important for the production of defect-free castings. The effect of various processing parameters to form a uniform cylinder during the horizontal centrifugal casting process has been discussed. The microstructure, tensile strength, impact strength, and hardness of cylindrical components have been discussed. The uniform cylindrical component was formed above 600RPM of mold rotational speed. At 800RPM better mechanical properties were observed. Also, finely structured grain sizes with high hardness values were observed when compared with other rotational speed.
