Because the metal is plentiful, light, ductile and corrosion resistant (the surface is covered by a stable, tough oxide that protects the metal underneath). The only drawback is that aluminium takes a lot of energy to smelt.
Aluminium is 99% reusable since it is resistant to oxidisation.
An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
Most are made with aluminum most certainly fly.
Aluminum
I would think it is made of Aluminum.
Aluminum is made out of aluminum ore.
Probably aluminum and plastic.
No - pure aluminum is much too soft and weak for any industrial purpose. It would be made of a carefully crafted aluminum alloy, which would contain aluminum and several other metals.

aluminum is not made from another metal, it is not an alloy. aluminum is a pure metal, made purely of itself.
No but it is made of aluminum which is the most prevalent element in the earth.
aluminum
They are made of Aluminum because aluminum gathers and stores heat.
