Aluminum Body and Lightening
Aluminum wiring was band many years ago because it can cause house fires when arching. This is what happened when lightening hit an aluminum body Ford pickup. :E Clicky

That is not the whole story !
Aluminum wiring was band because it was incompatible with the contacts used in most junctions (not true any more) and the wire was not properly sized.
Aluminum wire is widely used for entrance cable on even some very large branch circuit. If you had a 50A 240VAC trailer outlet added to your house, it is a 50/50 chance the electrician used aluminum wire.
NM-B cable (commonly called Romex) is only available in copper. The most common single strand wire used in residential and industrial application (THHN/THWN) is only available in copper.
