In the USA, most electricians are using more aluminum these days due to the cost of copper.

"cost of copper"

Last I checked, it was $1.25 a foot for 12/2 copper [50 foot roll]. Yikes!!

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.

—”In the USA, most electricians are using more aluminum these days due to the cost of copper.”

For residential?
Perhaps where you live?
I’m related to two electricians and hear about it often.

“The wiring itself isn’t a problem; aluminum conducts electricity safely. ... The U.S. Consumer Product Safety Commission (CPSC) reports that homes with aluminum wiring are 55 times more likely to have “fire hazard conditions” than homes wired with copper.”
