This European Standard specifies the composition and physical properties of cast unwrought copper products (refinery shapes) in thirteen grades of copper and nine silver-bearing copper grades. The refinery shapes included are horizontally,vertically and continuously cast wire bars,cakes,billets and ingots. Wire bars,cakes and billets are intended for fabricating into wrought products; ingots are intended for alloying in wrought and cast copper alloys.
A table indicating the refinery shapes in which each copper grade is normally available is given in Annex A. Annex B gives information on the relationships between electrical resistivity and conductivity of copper.
