An aluminum alloy is a compound that consists of primarily aluminum mixed with other metals. This can commonly be copper, magnesium, manganese, silicon and zinc. Alloys can either be heat-treatable or non-heat-treatable. Aluminum alloys are used in fan blades, sheet metals, truck frames and aircraft structures.

Scandium-aluminum alloys are used in the aerospace industry. The Sc-Al alloy creates a nano-scale precipitate that forms smaller crystals than other alloys, which are then used for minor aerospace components. Scandium is the most potent strengtheners of aluminum.
