Good question. The difference is unmeasurable. Both copper and aluminum 
have a permeability extremely close to unity (1). Copper is 0.999991 and 
Aluminum is 1.00002, so most inductance calculations use a value of 1. 
These particular materials won't vary with changes in current that would 
be detectable. So the inductance becomes a function of geometry and turns.

Take care,
Bart
