bronze and annodes

[PabloPicasso]

Do through hull bronze skin fittings (like the ones for sea-cocks) need sacrafitial annodes to protect them?

Is it safe to use copper based anti-foul over these fittings?

No, and yes.

The usual question is whether they really are bronze or something else. Bronze has good corrosion resistance and needs no further protection. DZR is a brass that is formulated for good corrosion resistance and also needs no anode. No other copper alloy should be used.
