The perceived dearth of American copper was magnified during WW2,all copper available was diverted to the war effort. Some interesting things about that...we all know about the zinc penny in '43..but did you know the calutrons used to enrich uranium for the bomb used electromagnets wound with pure silver? it was 'borrowed' from the Treasury,and had to be accounted for to the ounce..

Mining and smelting capacity increased by the end of the war,we began using our vast reserves of copper ore..we are currently 4th in the world in production.

A German would appreciate that,they were on the receiving end of most of our copper..
