Not all, most i can buy where i live are from aluminum so they don’t need it. Idk why anyone would use anything not aluminum for it.

Another option is to galvanize The thing, but thats pretty inefficient.

Btw aluminum is so corrosive that its cording from just being outside an oil, the difference to iron is however that the rust isn’t falling off and actually protecting the aluminum.

You need pretty strong chemicals to get through aluminum, wich isn’t a thing in most beverages.

Another advantage of tins is that they have a higher thermal conductivity, meaning they cool faster and more efficiently than glas or plastic.
