Another metal that can be used in linng copper cookware is tin, but you just have to be careful not to bring it up to its melting point of about 450°F.
Aluminum is commonly used in moka pots, along with all kinds of other cookware and food storage (like cans). The surface of the metal reacts with air to form a thin layer of aluminum oxide, which is resistant to corrosion, and can be thickened through anodizing.
I don’t know anything about anodized copper, but it’s also used in cooking.
Stainless steel is less conductive than copper or aluminum, but it certainly works fine in all sorts of pots and pans. For coffee, most travel mugs I’ve seen are steel, and you can get steel moka pots.
I didn’t find the right solution from the Internet.
