I doubt it's worth quantifying for signal connectors, not even those from moving coil cartridges, where electrolytic action in corrosion is the problem, not the initial resistance. Nickel is used with chromium in high temperature resistance wire, for heaters, but in a thin plate with large surface area, it will be micro-ohms or less, probably.
