Do copper-clad stainless cookware contain any aluminum?

No, copper-clad stainless cookware does not contain aluminum.

Here's why:

* Copper-clad cookware is made with a core of stainless steel, which is then clad (coated) with a layer of copper.

* Stainless steel is an alloy of iron, chromium, and nickel. It does not contain aluminum.

* Copper is a separate metal and also does not contain aluminum.

While some cookware might use aluminum as a core or bonding material, this is not the case for copper-clad stainless cookware.
