Makes you wonder if all the mismatch in metals is audible?
ABSOLUTELY!!!
For those wondering, here's the Electrical Conductivity order in terms of Gold (assuming Gold to be 100%)..
Conductivity
S/m*10^6
in % of gold 1 Silver (Ag) 62.89 147.80%
2 Copper (Cu) 59.77 140.47%
3 Gold (Au) 42.55 100.00%
4 Aluminium (Al) 37.66 88.51%
5 Brass, 10% Zn (CuZn10) 35.86 84.28%
6 Rhodium (Rh) 22.17 52.10%
7 Zinc (Zn) 16.90 39.72%
8 Brass, 40% Zn (standard) 14.94 35.12%
9 Nickel (Ni) 14.60 34.31%
10 Phophorus-Bronze (CuSn4) 12.00 28.20%
11 Iron (Fe) 10.29 24.18%
12 Tin (Sn) 9.09 21.36%
13 Phosphorus-Bronze (CuSn8) 7.50 17.63%
As you can see, silver & copper rules as the best electrical conductors. Gold is not bad but rhodium is poor...
richidoo - you should try soldering direct to rhodium, talk about a super real PITA!!!
