The name "aluminum" comes from the Latin word, alumen meaning "alum" which is potassium aluminum sulfate, a common hydrated base. Aluminum is a good conductor of electricity, resists corrosion, and can be hammered into thin layers (aluminum foil). Polished aluminum is highly reflective. Its weight and durability led to its use in the major structural components of modern passenger aircraft. It is, however, relatively fragile compared to steel, titanium, or advanced carbon fibers that are also used in this role. Aluminum is easily recycled from commercial and consumer goods to make new products. In the environment, the metal is slowly degraded back into mineral forms.
