    I can’t think of many things you encounter every day that just use straight iron. Only alloys that use iron

    Meanwhile, you’ll use very pure aluminum all the time

      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.

        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.
