SS and Bronze Corrosion
Ahoy Jim , Yes , of course there is galvanic diferential between SS and Bronze .
Personally , in above water applications,I would rather have my structural bronze parts turn green than to have the connecting SS part rust, pit , and crevice corrode. The bronze turning green with corrosion is a bit like zincs on the prop shaft, sacraficial .
The slowness of the silicon or aluminum nickle bronze to degrade to a non-structural approval is one of it's great assets .
Like Brion has said many times before,,,, " Always try to build in a reserve of neglect ", when fabricating and assembling structural rigging and other boat hardware . He is "Spot On" with this advice.
