But aren't most Rads made from aluminum?
Even then, Aluminum, while chemically unstable, is physically stable. It's true that Aluminum is one of the most reactive metals known - they make thermite out of Aluminum - but for the most part, only the surface corrodes. As it corrodes, it leaves behind a very stable "shell" that protects the metal beneath. If it gets scratched, they newly exposed metal is corroded instantly to form a new shell.
Stainless steel works the same way, because of the nickel in it. Unless I am ignorant of something, you should be able to use Aluminum in a loop with Stainless Steel, Brass and Nickel. It's just unplatted or uncoated Copper would would have to watch out for.
