THE necessity for the development of high strength structural alloys was accentuated by the rapid development of the jet engine, a power unit which brought the speed of flight to within reach of the speed of sound. This major step in engine potentiality put a new urgency on the need for high strength structural alloys to be placed at the disposal of the designer. This deficiency was diminished to a large extent by the production of the aluminium-zinc-magnesium-copper alloys. Once the potentialities were realized of this type of alloy having tensile strengths equal to the low carbon steels and a strength/weight ratio substantially superior to the aluminium-copper alloys, it found widespread application for primary aircraft structures. The approximate chemical composition of the (Al-Zn-Mg-Cu) alloys is given in table i and compared with that of the Al-Cu or duralumin type alloys.
