Abstract :
Which metals will continue to be used in increasing quantities? Already we are witnessing the phenomenal growth of the light metals. Military planes dictate the expansion of domestic production capacity to 700,000 tons a year for aluminum and 200,000 tons a year for magnesium, representing 5-fold and 100-fold increases compared with the 1937 peak output of the respective metals. When the war is over, efforts will be made to utilize this capacity.
