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
You as a human use pure iron. But non-animate objects, yeah mostly alloys
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.
Sounds like aluminum is a loner and iron plays well with others. I’d bet there is still more iron encountered every day than aluminum even if the aluminum is pure and the iron is alloyed.
I was super confused when I read “loaner”, I thought you meant loaning as in like borrowing. But then I realized you meant “loner”. Lol
