phosphor bronze for keel bolts
If considering stainless, I would usually recommend an austenitic such as 316 for its somewhat better resistance to corrosion in seawater. However, although the galvanic voltage for active 316 is -0.18v, the galvanic voltage of passive 316 is -0.05v.This might corrode your copper somewhat. My...- starship
