An aircraft is composed of aluminum by 70% in weight. Aluminum alloys has made the greatest contribution to the development of aircrafts therefore the aviation industry due to its lightness as well as the durability. After the duraluminium (aluminum-copper) alloy the most important future aircraft material will be aluminum-lithium alloys. With aluminum-lithium alloys 15% weight reduction of planes is possible.

The importance and usage of aluminum in terms of the defense industry is rapidly increasing. In rocket and missile systems different amounts of aluminum alloys are used. As of the type of rocket or missile, according to the infrastructure and parts , aluminum and products may be preferred.

In exterior structural components that are exposed to aerodynamic loads, generally heat treatable hard alloys which provide high strength are used.In production it is generally worked in the form of plates however in the body production parts or drafts are used which are formed by extrusion or molding technologies.
