It is copper that has a silver coating. It makes it easy to keep the polarity straight, it is not rocket science.
I hear you. Cut it. Do you see copper inside the strands? Not on mine, so it is not copper painted silver. And it is not actually silver on top of copper. So what is that silver wire made of? I say it aint copper. Not that it matters, but short of alchemy it aint copper.
"Place your bets, place your bets!"
I say tin, lead or aluminum or the most likely choices. Tin is my bet - just to piss people with "tin ears" off.
