Probably not, although I didn't submit it for quantitative analysis.

But I'll bet you don't have a pure aluminum radiator, either.  Aluminum is
pretty much always alloyed with things like silicon and iron.

So does copper.  You forgot to mention having to keep the antifreeze and
sacrificial anode changed on schedule, not parking it in a barn and
forgetting about it.
