Description
Soft, lightweight, silvery-white metal. Third most abundant element in the earth's crust.
Uses
Used for many purposes from airplanes to beverage cans. Too soft in its pure form so less than 1% of silicon or iron is added, which hardens and strengthens it.
Sources
Never occurs in free form. Obtained by electrolysis from bauxite (Al2O3).
Pronounciation (English)
ah-LOO-men-em
