Judy,

    The CDA web page (www.copper.org)  that I sent out before lists the
    alloy #75200 (they added the extra 2 zeros a few years ago too allow
    for more alloy designations ) It shows that it has .05% lead in it.
    That is a very small amount but you still should be aware that it is
    there. 

Jim
