I wouldn't boil in aluminum, personal preference though not for health or short term structural reasons. It just can't take heat like steel can, and most of them are lined. Linings bad, they melt.
Guyot's bottles are a single walled, unlined bottle. They tell you not to boil water in it, but that is because the sucker is going to be HOT and there is no handle. I might have poured tea in my first one, and promptly took a thumbprint off for a few days. But you can do it, and they stand up to it. (This one hadn't been used over a fire yet, nor frozen.)
