Note Davey is mostly concerned with dissimilar fastenings. as galvanic corrision can only be present in an electrolyte - fastenings are most at risk when the hull
material absorbs water
and produces an electrolyte which creates electical flow that eats up the dissimilair metal.
So, galvanized wire in contact with the end of a BRONZE, not brass, chainplate, or SS chainplate is a minor issue, compared with using the wrong type of fastener to secure the chainplate to the hull
BTW, wikipedia has some interesting disscussion and examples of galvanic corrision with dissimilar metals
