While I don't have access to information on every single cookware manufacturer and their product offerings, I can provide general information about common materials used in skillet construction.
Skillets or frying pans are typically made from a single material for their cooking surface, such as stainless steel, cast iron, carbon steel, or non-stick coatings. However, there are some cookware manufacturers that have produced skillets with layered or clad constructions, combining different materials for specific purposes.
In the case of copper or aluminum exteriors with a carbon steel interior, this specific combination is not commonly found. Copper and aluminum are excellent conductors of heat but are not typically used as the cooking surface due to their reactivity with certain foods and the difficulty of maintenance. Carbon steel, on the other hand, is known for its durability, heat retention, and non-stick properties when properly seasoned.
Clad cookware often consists of multiple layers of different materials, such as stainless steel, aluminum, or copper, for optimal heat distribution and retention. However, the cooking surface in such pans is typically made from a single material, such as stainless steel.
It's always a good idea to research and explore various cookware brands and their offerings to find the specific combination you're looking for. Keep in mind that cookware trends and product availability can change over time, so it's best to consult the manufacturer's catalogs, websites, or contact them directly for the most up-to-date information on their product offerings.
