cut Well, then you should NOT use diodes, because they stick all sorts of metal and semiconductors together.

I'm just not following what that has to do with temperature dependence?
temperature?
What might happen to the specific resistance of pure Pb when you increase the temperature by a couple of °C, from, say, 4.2K to 6.2K?

temperature?
I can find no reference to that, but since Pb has a transition
temperature of 7.175K, I'd expect its resitivity to remain zero at
any temperature below that.
Am I missing something?
temperature?
Hi John, I think Spehro was 'commenting' on your "Without exception" statement. If you'd said, "In general", instead....

Copper's residual resistivity is very greatly affected by magnetic impurities. Oxygen annealing to get rid of the unoxidized Fe improves the low temperature resistivity by some enormous factor, like turning 4N into the equivalent of 6N.

But all of the expensive wire is "oxygen free". ;-)

Most audiophools freeze solid somewhere above 77K.

So it increases by 3%, then :-)

Yes, for certain values of zero.

Now THAT, folks, is PKB!
Offload your narcissism, so that you are not quite damn annoying. You are a lot like a child that has been sprayed by a skunk and is proud of it and won't bath.

Bath?
Design some electronics. Post it here. Everybody will feel better, especially you.
