conducting metal

PRodQuanta

Does anybody know off of the top of their head:
1)The most conducting metal
2)A conducting metal with the roughest surface (looking for surface area)

pure metal or composite?

Off the top of my head:

1) if your talking about metals and conducters, the classic answer would be copper, if you want to keep things simple stick with his.

2)Well if you take a metal solid it's 'roughness' is not really a property of the metal you choose, more how it's been worked.

dduardo-
both.

Ze best conductor, she is silver, not copper.

Tom is correct, the pure metal with the highest conductivity is silver

The standard composite superconductor is NbTi (Niobi-Titanium) at 8K.

From Giacoletto:
@ 273 K
Ag (five 9s) 0.0147x10^-6ohm^.m
Ag ("normal") 0.0150
Cu (four 9s) 0.0158
Cu (O free, 99.95) 0.0153
Au (five 9s) 0.0219
(all in annealed condition --- cold working raises resistivity)

14-kt Au(cold worked) 0.0145
(annealed) 0.0150
