How Copper is Formed into Sheets

Casting. After the blocks of copper cathodes are melted, the copper is cast into a variety of shapes including rods, billets, cakes and ingots. The next process uses a long series of rollers to form the bulk copper into thin sheets of metal and finally into the large copper rolls we use here at Crescent City Copper (link to home page) to build all of our products.
