I think both thermal and heat conductivity increase in the sequence Au -> Cu -> Ag with Ag being the best conductor assuming the resistivity and heat conduction data are correct in this link: webelements.com

William and Glenn, Remembering back to my physics and chemistry days, I believe you and Glenn are mistaken and that Kis and GF are correct. Popular belief is that gold is the best conductor but silver is actually acknowleged as the best conductor in the scientific community. >>Silver has the highest known electrical and thermal conductivity of all metals and is used in fabricating printed electrical circuits and as a vapour-deposited coating for electronic conductors; it is also alloyed with such elements as nickel or palladium for use in electrical contacts.<< britannica.com minerals.net minerals.net encarta.msn.com Jerry

>Gold is the best conductor of heat and electricity. What! A cash flow expert, and now your a metallurgist. I assume you do neurosurgery also.

Sigh. From Encyclopedia Britannica (britannica.com): Properties, uses, and occurrence. Together with gold, and the platinum-group metals, silver is one of the so-called precious metals. Because of its comparative scarcity, brilliant white colour, malleability, and resistance to atmospheric oxidation, silver has long been used in the manufacture of coins, ornaments, and jewelry. Silver has the highest known electrical and thermal conductivity of all metals and is used in fabricating printed electrical circuits and as a vapour-deposited coating for electronic conductors; it is also alloyed with such elements as nickel or palladium for use in electrical contacts. Silver also finds use as a catalyst for its unique ability to convert ethylene to ethylene oxide, which is a precursor of many organic compounds.
