Yeah but I wouldn't want to use aluminum as a long term container to boil water in. In a pinch for several times but probably not more. I do know that polished aluminum canteens are fine to use for a liquid container (the US Army used them as GI canteens for many years and through WWI & WWII & Korea with no ill effects on the troops) and so is aluminum soft drink cans that are not only polished but have a factory coating on the inside. I would have a problem with rough unpolished aluminum for drinking though. I would also be wary that the aluminum will eventually leach off into the water (liquid) from the heat (basically become soft) of boiling. But the Army used stainless steel canteen cooking cups, not their aluminum canteens for boiling or cooking. There are probably aluminum pots, pans, and canteen cups on the market to be used for cooking but I would not want to use them, at least not long term.
I do have a problem with plastic as a liquid container even though the US Army from Vietnam onward adopted the plastic canteen. I do have one of these plastic canteens but the plastic taste makes any liquid coming from it, hard for me to swallow or keep down. Hotter climates (high temperatures) do make plastic soft. That plastic has to be leaching off into liquid whether it contains BPA (Bisphenol A) or not. I do believe that the military plastic canteen has been researched on BPA and/or other plastic hazards and doubt very seriously that it has any plastic hazards since it continues to be issued to US troops (unless they want to overload the VA hospitals). Unfortunately, limited amounts of BPA seem to be in just about any food or drink container currently so there is no getting away from it no matter what product for the most part for the time being. There is obviously reason for concern if many US states are now considering a ban on it. I have been seeing more products now being made with the "BPA Free" labels on them.http://en.wikipedia.org/wiki/Bisphenol_A
I have about two aluminum canteens, two stainless steel water bottles, and one plastic canteen. I use the stainless steel bottles more than any of the canteens as I keep them in the truck but I also keep an aluminum canteen in the truck also for belt carry.
