Modern Aluminium Alloys: A Survey of the Materials to Various Specifications Available for Use Available to Purchase

IN replying to the discussion on one of his many excellent papers to the Institute of Metals, the late Dr. Rosenhain once made a statement to the effect that it took industry approximately ten to fifteen years to develop for commercial use the advances in knowledge which resulted from the researches of such Institutions as the National Physical Laboratory. Whatever may have been the shortcomings of industry ten years ago, the outstanding feature in the world of light alloys during the past two or three years has been the tremendous increase in manufacturing capacity and the modernization of all methods of production. This has been a necessity, caused on the one hand by the progressive increase in size of engines and planes, and on the other hand by the Rearmament Programme, which has been necessary owing to the unsettled condition of world affairs.
