The use of elektron metal in airplane construction
This 1931 NACA technical memorandum, issued by the National Advisory Committee for Aeronautics, reports on using elektron, a magnesium alloy, in aircraft structures, written for engineers and aviation researchers. Its plates are black-and-white photographs of test specimens, machined parts, wheels, engine components and aircraft assemblies, showing sheet, tube and cast forms in close detail. A designer could take from them the look of skeletal lattice frames, curved ribbed shells and riveted metal fittings as industrial structural imagery.
