My first choice would be a 70/30 copper nickel alloy.

What commonly available alloy has the best corrorsion resistance
properties?
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.
Also, can anyone recommend a good metal rod, tube manufacter that
supplys their wares in metric sizes? (US based)
Thanks.
