Does the density of aluminum has something to do with its being one of the wonder metals of space age?

Answer 1

It is important for all the materials used in the production of all types of air crafts to have low density. Aluminium and titanium (and their alloys) are frequently preferred because they are low density metals.

Aluminium is certainly good for building cars and planes. Additionally it corrodes very quickly to form a layer of aluminum oxide on its outer surface that then prevents further corrosion, so it doesn't need painting. I'm not sure that qualifies it as a wonder metal. I really like memory alloys such as nitinol, that 'remember' the shape they have been annealed into - these metals have many wonderful uses from orthodontic wires to repairing arteries or working the flaps on stealth planes.

Answer 2

Yes, the low density of aluminum is one of the reasons why it is favored in space applications. Its light weight makes it ideal for creating structures and components for spacecraft, satellites, and other space technologies without adding excessive weight. Additionally, aluminum has good corrosion resistance and can be easily formed and machined, making it a versatile material for space exploration.
