Aluminum? Ick, hope it doesn't have to do any serious combat cuz it'll burn like a torch.

Aluminium, saltly water. Hmm, what's missing? How about a bit of mercury?

You don't even need to get it to ignite to waste it, mercury makes very short work of aluminium, especially in the presence of water...

I'm surprised given that one of it's suggested uses is mine sweeping that it isn't made out of composite materials like most modern mine sweepers. But yeah, Aluminium is a really bad idea on a whole.
