RE: Silver Cartridge Coils

Your point is well taken although I don't know how you came up with the number 4%. The three best conductors are silver, copper and gold in that order. Since silver is the best conductor of the three, if we let its conducting ability be equal to 100%, then copper falls in at 94.6% and gold equals 65.1%. I calculated these percentages from the table in the Wikipedia article in the link below.
Gold is often used in places where oxidation might be a problem such as switch contacts and connectors that are exposed to the atmosphere. Silver is the best conductor, but also the most expensive. Copper is much cheaper than silver and almost as good at conducting electricity. Therefore, copper is the most widely used electrical conductor.
Best regards,
