When you guys are talking about the different metals for all the different outlets and connectors, do you consider the plating process? I know that you can't always plate over some metals directly and have to plate more than once. For example, lets say you want to plate some brass connectors with gold. Before you do the gold plate, you may have to plate the connector with another metal like nickle first, and then do the gold. (To be clear, I don't know if you have to do this with plating gold on copper. I'm just using it as an example.)
