SonarQuest Silver Plugs have Nickel Layer?


Have been making some DIY AC cables and was about to buy SonarQuest Alloy Edition Silver Plated when I read this in the specs:

"Processing the copper surface, Surface Plated layer of bright nickel plating → Flash Silver Plated → Thick 4N Silver Plated → CRYO -196."

Wouldn't the nickel layer between the copper and silver screw up the high conductivity of the copper and silver? Went with the straight copper instead. Gold plated also has nickel layer.
