What is the term used for copper that has been rolled into sheets?

The term for copper that has been rolled into sheets is "Wrought Copper." This classification arises from the processes utilized to shape the metal. When copper is rolled, it undergoes mechanical working, which enhances its strength and allows for the production of thin sheets. The term "wrought" generally refers to metals that have been physically manipulated and formed, as opposed to those that are cast or otherwise shaped without direct physical alteration.

In contrast, options like pure copper refer specifically to the metal's elemental state without impurities and do not pertain to its processing or form. Cast copper involves pouring molten copper into molds, leading to a different texture and structure than what is achieved through rolling. Forged copper implies that the metal has been shaped through hammering or compressing, which diverges from the rolling process that defines wrought copper.
