Jerry,
There is a very little copper in steel. Without a metal spec book (books that describe the amounts of elements in various steels grades, such as 4130, 4140, etc., and other metals) I cannot tell you exact amount, but most have some from times in the past when I was looking up the different types.
Maybe another member can help both of us regarding the copper?
