This is because aluminium is not strong enough on its own.
The two wings of the airplane are made of aluminum.
Copper is too soft and weak.
they can be made of carbon fiber, aluminum alloy or titanium
Depends on the aircraft. Could be aluminum, wood, fabric, or fiberglass.
the Pinninfarina bodies are made of aluminum, composite metals and carbon fiber
Most cars have some aluminum in the structure, but for the most part, car bodies are sheet steel. The 1980s DeLorean was constructed from aluminum.
Some reasons include the light weight nature of aluminum, and the properties of aluminum that reduces its susceptibility to corrosion.See this link for some additional information: http:/www.historyofaluminum.com/usage.php
On the contrary it has plenty of meaning. Why not try and fly an airplane made of steel instead of aluminum. Think about it.
For being the first woman to fly an airplane and fly across the ocean ALONE
Yes. A lot of aircraft are built with aluminum. The aircraft industry would not exist as we know it without this amazing metal. Certainly there are some components that cannot be build from aluminum, but a large portion of the airframe and the skin of many planes are fabricated from aluminum.
Because it is stronger and lighter than other alloys, as well as being resistant to most forms of corrosion.
I can think of two reasons: lightweight (better gas mileage, etc.) and no rust
