Weldability of Friction Stir Welding using Aluminium Alloy with Pure Copper

Recently many reports on Friction Stir Welding (FSW) of various dissimilar systems such as Aluminium to Copper been reported.FSW of Aluminium, Copper has captured important attention from manufacturing industries, such as Shipbuilding, Automotive, Railway and Aircraft production. Copper and its alloys are widely used in industrial applications due to their excellent electrical & thermal conductivities, good strength, corrosion & fatigue resistance. The aim of present study was analogy of the microstructures and mechanical properties of friction stir welded joint of Aluminium to Copper plates in 4mm thickness.
