Just a quick Google will give you some basic information regarding this which is mainly for highly acid contents but I can provide scholarly articles if you want further evidence. Maybe I'm paranoid but I prefrr stainless where I can as it is far stronger. Personal preference here
Been using an alumimium pot for my kettle for the last 11 years.
My insanity has only increased a little in that time.
No, but seriously, there's nothing wrong with aluminium, it's an excellent heat conductor, and it's somewhat cheaper than the equivalent size SS.
And if you want to drill a hole for your tap etc etc, it's much easier than in SS.
I didn't like to mention that since using the aluminium pots if I stand to close to a microwave I piss myself and forget who I am.
Seriously there is nothing wrong with aluminium pots and pans, the aluminium in deodorants is a different story
