In plain English: Aluminum is a lightweight, shiny metal used to make cans and foil because it does not rust easily.
"The can in my hand is made of aluminium, which makes it easy to recycle."
Usage: Use the British spelling "aluminium" in most international contexts to distinguish it clearly from American English usage. This term refers specifically to the lightweight silver-white metal widely used in construction and packaging rather than any other material.
The word aluminium comes from the Latin words alūmen and -ium. It was first used in 1812 as an alternative spelling for aluminum.
