A method of making an aluminum alloy containing titanium includes heating a first composition to a first temperature. The first composition includes aluminum. The first temperature is greater than or equal to a liquidus temperature of the first composition. The method further includes adding a second composition to the first composition to form a third composition. The second composition includes a copper-titanium compound. The method further includes decomposing at least a portion of the copper-titanium compound into copper and titanium. The method further includes cooling the third composition to a second temperature to form a first solid material. The second temperature is less than or equal to a solidus temperature of the third composition.
