Successful joining of dissimilar materials is important in order to optimize mechanical properties such as strength, density, corrosion resistance, etc., for several applications. Al-alloys, particularly hardenable ones, are widely utilized in automobile and aerospace industries owing to their excellent properties. Besides all Al-alloys are light-weight they exhibit different properties. For instance, AA6061 alloy display excellent corrosion resistance whereas alloy AA7075 possesses a very high strength. Thus, it is worth to search the joinability of dissimilar Al-alloys plates and their performances. In this study, dissimilar Al-alloys joints (AA6061-O/AA7075-O and AA6061-T6/AA7075-T6) were produced using friction stir welding, which is well demonstrated to produce reliable joints in similar Al-alloy plates, employing two different sets of weld parameters. Detailed metallography, micro hardness measurements and tensile testing were conducted in order to characterize the joints obtained and to determine the effect of temper condition on joint performance.
