The joint effect of scandium and zirconium on the strength properties and the electrical resistivity of industrial Al–Mg2Si–based alloys has been studied. The additional alloying of Al–Mg2Si alloys with transition metals leads to substantial grain refinement of the aluminum solid-solution and, therefore, an increase in the strength properties of the industrial alloys.
