Aluminium (Aluminum) Manufacturing Methods | .

Why is it Aluminum in the USA but Aluminium in the rest of the world? Sir Humphrey Davies (English chemist) named it Aluminium but for some reason Webster's Dictionary in the USA - which is their version of the Oxford dictionary - spelled it Aluminum back in 1828. Finally, the American Chemical Society formally adopted "Aluminum" in 1925.
