Aluminum-silicon alloys acquiring extensive industrial attention due to their superior resistance to rate of wear and elevated strength to weight ratio properties. Though the properties of the materials substantially depend on the manufacturing process they involve. Thus many industries focusing on new manufacturing methods to produce high-performance alloys. In this present study, AlSi (16-18) alloys were prepared by new CRSS (combined rheo stir squeeze) casting method with rapid-solidification process under T-6 condition. CRSS-T6 as casting process enhances the microstructural and mechanical properties significantly by 40-70%. Whereas, the maximum value of hardness (179.37) was found with AlSi17Cu3.5Mg0.8 with CRSS-T6. The improvements in hardness and elastic properties were mainly ascribed to size, distribution, and morphology of Si-particles because of its manufacturing process. SEM, advanced metallurgical microstructure and EDS analysis techniques are used for the surface morphologies observation. Moreover, Brinell hardness tester and Tensometer are used for the characterization of mechanical properties
