conducting metal
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) Paden Roder |

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. |

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 |
