Question

aluminium and not iron is used to make aeroplanes. why?​

Answer 1

Answer:

Aluminum is the perfect material to use when manufacturing airplanes, thanks in part to its unique properties and characteristics. It's strong, lightweight, predictable and inexpensive. Steel and iron are both stronger than aluminum, but strength alone isn't enough to justify its use in aerospace manufacturing...

Answer 2

Aluminum  is used on most types of aircraft because it is lightweight and strong. Aluminum alloys don't corrode as readily as steel. ... It has also been used for the skin of some high-speed airplanes, because it holds its strength at higher temperatures..
