Abstract: The present disclosure relates to aluminum based alloys and a method for producing the aluminum based alloys. The method comprises acts of, casting of the aluminum based alloy in a chilled casting mold. Then, aging the cast aluminum based alloy at a first predetermined temperature for a first predetermined time. The aging results in the formation of a first precipitate. Followed by this, solutionizing the aluminum based alloy at a second predetermined temperature for a second predetermined time such that the major alloying element is dissolved in aluminum matrix without much affecting the first precipitate. Then, aging the aluminum based alloy at a third predetermined temperature for a third predetermined time. The aging results in the formation of a second precipitate.
