aluminum

Aluminum is the chemical element in the periodic table that has the symbol Al and atomic number 13. It is a silvery and ductile member of the poor metal group of chemical elements. Aluminum is found primarily as the ore bauxite and is remarkable for its resistance to oxidation (due to the phenomenon of passivation) and its light weight. Aluminum is used in many industries to make millions of different products and is very important to the world economy. Structural components made from aluminum and its alloys are vital to the aerospace industry and very important in other areas of transportation and building in which light weight, durability, and strength are needed.
