Developments in Aluminum Alloys in Relation to Economies in Aircraft Construction

Abstract

Abstract This paper reviews the mechanical properties and corrosion resistance of available aluminum-alloy structural materials, and as to the fabricating situation, discusses the status of technical information, equipment, and practices (forming, jointing, and corrosion prevention). A summary coordinates these matters to show what has been accomplished and the general direction of present developments, with the thought that the present lull in production provides an opportunity to plan for the future and conduct the indicated experimental work. The discussion is limited to the structural parts of aircraft, such as fuselage and wing and control surfaces, omitting power plant, landing gear, and accessories.
