Element may be either copper only, or zinc-plated copper for superior corrosion resistance. Scale and corrosion are a common cause of failure for copper heating elements. Here is some helpful information about zinc plating: https://www.sharrettsplating.com/blog/corrosion-resistance-of-zinc-plating. Zinc plated elements appear to be stainless steel but are not.

Zinc-plated copper elements are made in USA and are slightly shorter with no difference in performance. Copper elements are made in China.
