allow me to point out to you that the surface effect is negligible at
power line frequencies - at RF frequencies it becomes significant. the
coating is for corosion resistance. To study further, look up surface
effect - you can derive it yourself if you care to solve maxwell's
equations as a function of freq.

Very interesting!

Which then suggests brazing electrical connections?

You omitted alum, nickel, gold.

Old wiring, at least in parts of NY, were soldered AND wire nutted!!
I think soldering of splices in house wiring is a very good, safe idea.
Just not all that convenient.

Now here's sumpn fer you electricians:

I have old cloth-covered #9-10 solid wire in my old cloth-covered house,
and sed wire is, I believe, *silver plated*!!!! Well, plated w/ sumpn,
brite and shiny.
If it *is* silver, it is a marvelous idea, because sposedly the bulk of the
current density in a conducting wire lies on the surface of the wire.
If it's tin plated, the question is then *why*!
Nickel??

Might make sense then, to silver, or even copper plate aluminum wire.
Like our pennies.
