The zinc itself is conductive, however, conventional chromate conversion coatings add surface resistance that lower the anticipated conductivity of pure zinc. Furthermore, organic topcoats and other sealers intended to boost the corrosion resistance of chromated zinc typically degrade the surface conductance even further.
The differences in electrical conductivity of various materials used in marine electrical products are often not well understood. Making assumptions about the electrical conductivity of a material because it looks similar to another conductive material of known ampacity can lead to disastrous results.
Want to convert current brass terminals to zinc plated steel ... The first problem that you will run into is conductivity. Brass carries 1/4 the current that copper will. Steel carries 1/8 of copper. Any break in the plating will cause the iron to corrode many times faster than brass will. You might look at a heavy silver plate, it carries ...
In the zinc plating process a bond is created between the zinc and steel forming an iron rich alloy. When corrosion appears, the zinc corrodes before the steel, allowing the steel to go unmarred. The zinc plating process can be considered an excellent primer for paint surfaces, with the paint protecting the zinc, giving a lasting protection.
Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity ...

Electrical conductivity is the measured amount of current generation created on a metal target’s surface. More simply, it is how easily an electrical current can flow through a metal. Which Metals Conduct Electricity? While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive.
