brass and nickle silver

[Bob C]

Jim, Hi ! While it's true that copper is an excellent conductor, you are correct - it's oxide (cupric oxide) is very poor. While it may seem logical that less conductive nickle silver would have an even less conductive, that's not how chemistry works. I don't have the proof,(though will spend some time checking for evidence) the molecular configuration of nickle silver oxide may be nearly as conductive as the alloy itself. Chemistry is a BEAR, and does not follow standard logic in its operations. Hope I can at least find a citation. :ugeek: Bob C.
