    I've cast copper in an investment casting setup, and it went
    oka-a-y, but it tends not to like to flow well into the mold, and as
    it has one temp for both solidus and liquidus it might not make for
    detailed castings as would an alloy. 

    Put a little bit of tin into the copper, like 5%, to help it flow
    better and give it a bit of a freeze range. 

    Oh, and call it bronze.
