Yes, copper clad.
In simple terms, there is plating, washing, and cladding. Plating is a thin layer and washing is even thinner. Both are electro-chemical processes. Cladding is a mechanical process where copper and steel for example are pressed together under great force, such as in a rolling mill. The sheets of clad steel are then punched into discs, formed into cups, and further processed into cases and jackets. The thicker cladding helps reduce tool wear and leaves a protective coating on the finished product. Although plating and washing have been used in small arms ammunition, most "bi-metal" cases and jackets are clad.
A common example of cladding is some U.S. coins. If you look at the edge of a quarter, dime, half dollar, you will see a copper core sandwiched between cupro-nickel. Post 1982 cents are copper plated zinc and do not have this same appearance.
