Review on recent progress in Al–Mg–Si 6xxx conductor alloys

The mechanical strength and electrical conductivity (EC) in Al–Mg–Si 6xxx conductor alloys are key characteristics but mutually exclusive properties. This review paper critically elaborates the methods to enhance conductivity. These include an optimization of main alloying elements (Mg Si), addition other elements, melt treatment, applying modified thermomechanical treatments, maximizing area reduction (severe plastic deformation) wire drawing. Besides, impact various microstructural features on properties is addressed detail using resistivity models. A principal conclusion drawn this that ought be enhanced by creating barriers (such as sessile dislocations precipitates) for dislocation movement while having a less detrimental effect Considering potential alloys, future directions outlined.
