When the British say Aluminum, it sounds like the most badass substance ever discovered by man. If someone from England told me they were going to fire a rifle at me while I took cover behind a barrier made of Aluminum, I'd be in line to try it out.
It is pretty badass as it happens. It used to be so highly prized that bars of it were displayed beside the French crown jewels. In fact it is said that Napoleon III had a dinner set made from it for only his most honoured of guests. Amazing!!
Plus it's highly resistant to corrosion, fantastic!
