Voice Coil Spotlight: New in Voice Coils | audioXpress
Aluminum has 61% of the conductivity of copper. An aluminum conductor’s cross-sectional area must be 56% larger than copper for the same current carrying capability. The need to increase the thickness of aluminum wire is a consideration in its use in tight voice coil gaps—especially as it expands more than copper voice coils when hot. Voice Coils: A Tutorial | audioXpress Copper wire is most commonly used for speakers, although aluminum and copper-clad aluminum wire (CCAW) are also used. Copper is more conductive than aluminum and substitution of aluminum for copper requires a larger diameter wire for the same conductivity. Copper offers superior strength and is much easier to solder to than aluminum. Copper Coil vs Aluminum Coil in AC: Which is Better in 2021?

In this regard, copper wins. Furthermore, another pro for copper is the ease of repairing the copper coils in the field if they become damaged. Finally, aluminum coils, if damaged, are tough to fix and often need to be replaced. Aluminum voice coils? Why? | Headphone Reviews and Discussion ... Copper is a somewhat (~1.7x) better conductor than aluminum, but is much (~3.3x) heavier. So, the latter is a better choice overall, since minimizing the mass of the voice coil is important. Silver is not used for the same reason.
