Hi,

When I worked at the shipyards they always welded "zincs" on the hull of ships to prevent electrolysis due to the dissimilar metals of the steel hull, brass valves and bronze screws..........

They used "zincs" as the sacrificial metal to protect the others....

Zinc is a more active metal so that it would be sacrificed and not the ship.....

If you put zinc in an engine with an aluminum intake and radiator they will be sacrificed to protect the zinc.....

A more active metal must be used for protection.....

Aluminum intakes and radiators need a magnesium anode in the coolant (water) for protection.....

I also found them attached to radiator caps.

BTW: My heads, intake and radiator are all aluminum on an iron block..

Learning something as I go.
