Does the tinning-coating replace where copper would have been in
the overall wire and tinning is of higher reistence?
Is flexibility affected?


Tin has a much lower conductivity than copper, and as RF travels on
the surface of a conductor, it would attenuate RF and high frequency AC

Is that why most, but not all, teflon insulated wire was silver plated?

Most of my TFE coated wire is not silvered butl is tinned. All TFE wirewrap is
silvered.
