What commonly available alloy has the best corrorsion resistance

I am building a chamber that needs to last 500 years. It will be
indoors, but I need it to resist the effects of time and the elements.
I added commonly because I cannot afford some rare exotic metal.

In 500 years it is unlikely to still be indoors. Bronze ship nails have
survived 2000 years of salt water immersion so that is a good start.
