Really now? I thought most steel had way more carbon & chromium/nickel/manganese than that. I guess I underestimate how little is needed to make iron no longer mushy.
It is mainly only in stainless steels that have anything other than iron in high concentrations, they might have something like 30% of their weight elements other than iron
Pure aluminium is only used when you need to have very little reactivity.
General construction steel has >98% weight iron. Around the same as most aluminium alloys.
