There is no such thing as “just” aluminum (unless you’re extracting ore) it is all alloy of differing concoctions. Even your beer can is an alloy specifically chosen for that lone purpose. I work in aluminum die casting, we use three different alloys for different parts according to the application and customer demands. There is no pure aluminum.
I quite agree. But alloy metallurgy is so ridiculously complicated I can’t do more than opine that there might be something that aluminum could be doped with to make it much better for vehicular use.
Just wondering, have you seen any transparent aluminum? I am so hoping that somebody can figure out a way to mass produce it.
