Abstract In the past few decades, lightweight materials were become a global concern due to effective and sustainable are evidence most popular utilizing in industrial sectors. This research would concentrate on actions taken by local governments across India that resolve hazardous waste in an environment-friendly and key component to cost reduction and the recovery of waste content. In present work was focused on the utilization of solid waste (PKSA) with TiO2 and SiC nano particles are used as reinforcement materials in reducing material cost for extensive applications in automotive sectors. An attempt was made in varying different five weight fractions (0, 3, 6, 9 and 12%) to develop aluminium based nano-composites using modified gas injection ultrasonic probe double-stir casting process. A drastic improvement in mechanical and physical properties was observed with the incorporation of reinforcement content to aluminium alloy. The mechanical properties such as micro-hardness, tensile, impact and flexural strength were analyzed. The size distribution and physical properties like TGA, porosity, density were tested for both Al alloy and aluminium nano-composites. Microstructure analysis is taken using SEM and EDS, XRD has been analyzed. The results showed in this study are the benchmark against compatible alloys and metallic implants. Keywords Solid waste .

1 Introduction The composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Composites are “tailor-made” materials in which two or more phases have been combined to yield properties not provided by constituents alone. Composites are not only used in structural application but also used for electrical, thermal, tribological and environmental applications [1]. Aluminium alloys are lightweight and easily recyclable and are beneficial for industries to enhance technology. The 2XXX, 6XXX and 7XXX series of aluminium alloys have been used widely as matrix materials for making composites. The 7075 alloy exhibits high specific strength, high rigidity

and good corrosion resistance as compared to other alloys [2]. Nano-composites are currently gaining widespread popularity for producing higher toughness, increasing wear resistance and longer fatigue life, in addition to lightweight materials, compared to other conventional alloys. More researches are currently focusing on the development of aluminium-based nano particles to inve
