There is a new alloy of aluminum that dissolves in water. Think of the possibilities! BBB-9R
What possibilities can be derived from the alloy?
Water soluble Bradley Fighting Vehicles?
Does not seem likely.
…judging from the level of the factoids on the rest of the page (“Thomas Crapper invented the toilet”, “there are 10 billion tons of gold in sea water”, all obviously Copy and Pasted from other trivia/factoid websites), it’s probably a case of somebody somewhere misunderstanding something that somebody read in Popular Mechanics “What’s New”.
Searching Google for “aluminum alloy dissolve water”. Hmm…
Okay.
I’m guessing at the source of the factoid possibly being the following train of thought:
[ul]
[li]Beryllium, as salts, will dissolve in water.[/li][li]There is a new beryllium-aluminum alloy.[/li][li]Therefore, there is an aluminum alloy that will dissolve in water.[/li][/ul]

And anyway, why would you want a metal alloy, made from a metal that is already famous and extremely useful for being strong, light, and non-rusting as is, that would dissolve in water? “Uses”? Absolutely none, IMO.
