Copper transfers heat better than Aluminium, but costs much more (over 3x as much).
Most companies would rather use copper for critical surfaces (direct contact with the processor, or heatpipes) and aluminum for the heat dispersal fins.
Some companies make all copper heatsinks (such as zalman)

The best coolers use both.
Copper is able to absorb and trasnfer more of the heat vs aluminum, but alluminum is able to cool faster then copper.
Thus the best coolers have copper touching the cpu and copper pipes going into aluminum fins. Thus the heat is efficiently moved away from the CPU with the copper, and its temperature reduced by the cooler aluminium

I may be wrong but i believe it is also easier to make thin aluminum fins vs copper, and when it comes to thermal temperature changes them more effected surface area the faster/more effective the thermal difference will be.
EDITED:
Did some research on this.
Alluminum is cheaper as a mateiral in general but also cheaper/easier manufacturing to make into thin fins.
Since the more fins (IE Surface area) you can put into the cooler the better it will be heat dissipation you are better off with say 100 alluminum fins then 70 copper fins despite copper being a superior metal for heat trasnfer.
Besides economics of materials the other factor is joints. Copper would require soldered joints which are inferior for heat transfer.
Lastly an all copper heat sink would wiegh more then a hybrid and so all copper versions of large coolers like the hyper 212 evo might actually be too heavy for the motherboard/socket and cause damage.

boosted1g covered it pretty well. An important aspect is Aluminum being less weight & mass for a given size dissipates heat faster after the energy source has been removed. Good for when the system is turned off. No so much when the heat source is active.
