Abstract: The aluminium composites are engaged in most of the aerospace and automobile applications. To improve the survival of aluminium in extreme environment such as nose, wings, and floors of aircraft improved properties are essential. In this current study, two different material with different properties are joined together to form a new bimetallic material. Softer Al-6061 is used as sleeve and grade II Ti is used as core were prepared through the co-extrusion process at a temperature of 400°C with the ratios of 2:1 and 2:0.5. Taguchi technique is adopted to verify the optimized process parameters of the co-extrusion process and found the most influencing factor for the hardness improvement. The fabricated macro composites are characterized, and mechanical and tribological properties are analyzed. The SEM is used to analyze the bonding characteristics of the materials. The properties such as resistance to point load and the bimetal composite tensile strength are tested using the hardness tester and UTM. The corrosion behaviour of the composite is tested using a polarization test. The development of the diffusion layer is observed at the boundary of Al-Ti material, and the bonding is improved. Compared to aluminium alloy and 2:1 bimetal composite, the co-extruded Al-Ti with the ratio of 2:0.5 bimetal composite ratio shows better microstructure and mechanical and tribological properties. newline newline newline
