Steel may soon replace brass in U.S. shell casings; and if it does, the substitution will cut by nearly 50% 1942's estimated copper shortage of 770,000 tons...
...been found that some of steel's former disadvantages can be overcome by plating it thinly with copper. This protects the steel from 1) rust, 2) damage by powder fumes, which corrode unplated steel casings so badly that they can be used only once, though brass casings can be re-used four times. Copperplated steel casings, however, seem to be resistant enough to be re-used 15 times-a great saving even though steel is harder to tool in the first place...
This week, while G.E. is starting work on a giant 100,000,000-volt model, Kerst is shipping his betatron to his laboratory in Illinois to see what discoveries he can make with it. Its electron beams have already penetrated inch-thick aluminum, made copper radioactive. Its medical applications, like those of the cyclotron which once struck the bewildered public as a useless device, must be explored. In time the betatron may be able to produce earthborn artificial cosmic rays, whose fantastic energies - hundreds of millions of volts - now smite the earth mysteriously from among the stars...
...Because the temperature ran to 150° F., Magma Copper would have abandoned its 4,600-ft.-deep Arizona mine. But air conditioning pulls the mercury to 90° F. and the mine is producing at record clip...
Metals. Aircraft-parts makers and other metal fabricators have been held back by the metals shortage, especially copper. So the mines of Anaconda, Phelps-Dodge and Miami last week jumped from a sixto a seven-day week. (Kennecott has operated day in, day out for more than a year.) Production increases in the first three companies alone will add perhaps 50,000 tons annually to the U.S. copper supply, an amount equal to 5% of 1940's entire U.S. production...
