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

[–] [email protected] 2 points 2 months ago

Perhaps so, but one might argue that human tech relies more on iron than any other metal - because of its magnetic properties. We need iron to generate and manipulate electricity.

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.

[–] [email protected] 3 points 2 months ago

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

sounds like a good argument for iron.

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

Oops, my bad lol

Pure virgin aluminium vs chad alloyed iron

[–] [email protected] 8 points 2 months ago (1 children)

You as a human use pure iron. But non-animate objects, yeah mostly alloys

[–] [email protected] 12 points 2 months ago

Uh, I hate to break it to you, but literally all the iron in the human body is either part of a protein or bound to other molecules. It's not an alloy per se, but it isn't exactly pure iron
