Sacrificial anode strap material

[Nick55]

I am retrofitting zinc anodes to protect carbon steel subsea.
The anodes have a steel piece cast into them. The electrical connection to the structure to be protected is made using copper wire (multistrand insulated, crimp lugs on the ends) from the steel anode insert to the structure. Is copper suitable for this ?

I don't see why not. I don't work in this field, but I don't think the Cu will have a problem, nor the steel-unless the Zn dissolves completely away.
