I would definately go with copper because here is the deal:
If you assign copper a value of 100 for it's "Relative thermal conductivity" then the following table applies:

Silver 108
Copper 100
Gold 76
Aluminum 56
Magnesium 41
Iron 17
Steel 13-17

Table 6-1 Smith, "Structure and Properties of Engineering Alloys, 2nd ed." 1993
(partially reproduced)

As you can see the thermal conductivity for copper is almost twice that of Aluminum. You may get similar results with well designed blocks if the copper is significantly alloyed (structural grade copper, adding even small ammounts of strengthening elements reduces the conducitvity significantly.)
