I'm attempting to write a story set in Eric Flint's 1632 universeIn the story, my characters are students who are working on part of a rocketry project. As they design their new rocket, they find that the material they are using, steel, is too heavy for the design and they have to find something lighter.
Now, the obvious answer to this question would be aluminum. But the canon states that the nation they are in can't produce aluminum from bauxite ore yet. I think I found a way around this.
There should be plenty of aluminum already in the universe - in the form of cans and foil (both the Reynolds Wrap type and foil pans). My question is this - can aluminum from cans (alloys 3004 and 5182) and foil be melted down and combined with other metals to form a new alloy that would be suitable for use in unguided rockets?
Thank you in advance.
