I have a stupid question for everyone. Is the copper in wiring made from pure copper (not accounting for negligible impurities), or is it an alloy of some sort?

Not only is it essentially pure copper, it is what is known as "oxygen free" copper.

"oxygen free" copper
They are required to use it on sattelites and on the space station.

Ya mean,... those guys selling the "oxygen-free" interconnects at $100 a foot are charging for a feature the $5 RCA cables from Radio Shack already have??? I'm shocked, I tell you! Shocked!!!

With oxygen free copper, the electrons sweat less.

Yes, wire is made from pure copper. Even small amounts of impurities can greatly reduce conductivity.

Just imagine if the only good conductor of electricity was mercury. Instead of copper wire, you'd be using rubber hoses filled with mercury. Slices would be fun.... Talk about leakage.

SOme audiofools might be convinced that mercury filled garden hoses for speaker cable gave the music a "fluid" sound....

Heard, that back in WW2, some buildings built for the Manhattan project (A bomb development) were wired with silver wire, as copper was in short supply.

Not buildings, AFAIK, but the electromagnet windings and busbars for the calutrons at Oak Ridge, TN, used for uranium isotope separation:

They borrowed 15,000 TONS of it from the US treasury...
