Not for normal branch circuit wiring. The only place aluminum wiring is used is for main feeds. Aluminum branch circuit wiring was tried decades ago. Mostly in mobile homes and in some homes. Caused a LOT of problems/fires. Problem is the dissimilar metals contacts with receptacles/switches, etc. For main feeds, a no-oxidization compound has to be used.

Not for 15/20 amp circuits where 14/12 gauge copper is normally used, but for 30 amp and larger circuits 8 gauge and larger aluminum is commonly used. And these are technically branch circuits, and could feed a range, air conditioning unit, etc.
