The entire house, every outlet, switch, box, everything is Al from 1967.

Because we bought the house with an FHA loan, we had to have the proper co/alr outlets put in everyplace including for GFCIs and switches. I've still had a few a couple of "sparky" incidents in the last 14 years. I've gone back through the switches and outlets (originally done by an electrician) and added noalox to all of the connections and tightened them up, and yes, I've had wire break near the end where it gets bent and unbent to wrap around connections etc....

I know that properly done Al should be fine, but in the future, I'll stick with copper since it's more robust and you don't have to worry as much that it's been "properly" done.
