A spray-formed billet of the alloy is prepared by: charging aluminum and the other elements that are to make up the alloy into a crucible; melting the elements in the crucible to form the alloy; pouring the melted alloy through an atomizer to atomize the alloy in a spray chamber; and depositing the atomized alloy onto a collector disc at the bottom of the spray chamber to form the desired spray-formed billet. The billet can then be forged into a shaped product, such as an aircraft inboard main wheel half.
