A builder in Peoria AZ uses aluminum wire for AC compressor. After all the

Probably varies regionally. Why not call an electrical supply house in Phoenix

BTW, you should know that it's not valid to compare #6 copper to #6 aluminum,
because their ampacities are different. Compare #6 copper to #4 aluminum.
