Question about: conductivity: gold, silver, copper, and aluminum.

Gold should plated over nickel because gold is pourus, and nickel is not. If you use gold only, then you probably want gold thicker than at least 50 millionths.

Gold contacts for low voltage signal circuits are a great advantage at little cost.

However, there are some environments where gold is even a problem. Here a reed switch may be a better choice.

Thanks for your time…

Electrical conductivity only matters when the wires have exactly the same diameter and length. Audiophiles get sold on Silver wires all the time.
