There is also a serious shortage in alloy metals used in jet and other high-temperature engines. All the world's resources of such scarce alloys as tungsten and nickel will not fill U.S. needs when production hits its peak. Defense officials are pushing a search for substitutes. So far, little luck...
...back into operation. Before Korea, there were 440 of these plants, worth $7.5 billion, in mothballs or on standby status. By May, more than half of them (344) were either back in production or about to be. Included are 15 out of 17 aluminum plants, all of the ferro-alloy plants, all but eight of 54 gun and ammunition plants, and 60 out of 77 shipyards...
...armed services use the lead-alloy Comet models ("accurate down to the thickness of the lacquer") to teach identification, demonstrate naval, land and air maneuvers on miniature battle grounds, and practice range-finding for gunners. Working from photos, blueprints or handmade models supplied by the armed forces, Comet's 50-man production line is ringed with the same security as many another defense plant. In an emergency, Comet's diemakers have turned out models of a weapon in 72 hours, from drawing board to finished product. At the time the first Walker Bulldog tanks rolled off the Cadillac...

Pratt & Whitney has already made big gains in solving the problem.lt has worked out high-alloy mixes which eliminate the use of columbium completely in the J-48. It has also reduced the use of other critical metals to a mere fraction of a pound per engine. Others have developed substitutes which permit existing supplies of the critical metals to be stretched 15 times farther...
