All kinds of aircraft use aluminum alloy as the main structural material. Skins, beams, ribs, stringers, bulkheads, and landing gear on aircraft can all be made of aluminum alloys. The amount of aluminum used in the aircraft varies according to its purpose. Commercial aircraft that focus on economic benefits are widely used due to the low price of aluminum alloys. For example, the aluminum alloy used in Boeing 767 passenger aircraft accounts for about 81% of the weight of the body structure. Military aircraft relatively reduce the amount of aluminum due to the requirement of good combat performance. For example, the F-15 high-performance fighter with a maximum flight speed of Mach 2.5 uses only 35.5% aluminum alloy. Some aluminum alloys have good low temperature properties, are not cold and brittle under -183～-253[2oc], and can work in liquid hydrogen and liquid oxygen environments. Therefore, it is a good material for the manufacture of liquid rockets. The fuel tanks, oxidizer tanks, inter-tank sections, inter-stage sections, tail sections and instrument cabins of each stage of the "Saturn" 5 launch vehicle that launched the "Apollo" spacecraft are all made of aluminum alloys.

The crew compartment, front fuselage, mid-fuselage, rear fuselage, vertical tail, flaps, elevons and horizontal tail of the space shuttle are all made of aluminum alloys. The main structural materials of various artificial earth satellites and space probes are also aluminum alloys.
