ABSTRACT:
This invention relates to master alloy hardeners for use in preparing aluminum base alloys. The respective concentrations of the alloying elements in the master alloy hardener are a multiple equal to or greater than 2 of the concentrations of such elements in the base alloy, and the ratios of the alloying elements in the master alloy hardener to each other are the same as the ratios of the alloying elements in the base alloy. After the aluminum base alloy and the concentration of each alloying element therein are identified, a desired multiple of such concentrations is determined. An aluminum master alloy is prepared that contains the alloying elements at concentrations equivalent to such multiple of the corresponding concentrations of the elements in the base alloy. The master alloy hardeners are added to commercially pure aluminum to provide the desired base alloy.
