Aluminum alloy for ocean front application?
Aluminum alloy for ocean front application?
(OP)
We have an assemly that is sometimes installed on ocean front sites. It was originally designed for inland applications using aluminized steel for most of the sheet metal parts. Due to the corrosion we see now, we are considering a change to 316SS or aluminum. The question is which aluminum alloy.
The parts are presently 16 gauge steel and there is no welding, only punching and forming. Some of the current parts are painted with a two-part epoxy but we may decide to leave all unpainted rather than deal with an aluminum painting issue.
Any suggestions?

From my experience with hard anodized 2XXX-T6 aluminum alloys,used in window frames in coastal environments in Southern California,pitting became a big problem from an esthetic standpoint. Many were replaced.

It has been years since I last dealt with anodize. Any thoughts on costs, $/square inch, $ per pound, etc.?
