I remember some time ago that Al wiring has bee discussed by this learned group,however I don't remember the details.
I received a call from a home owner that has Al wiring through out their 2500 sq ft house(with a FP panel)built in Florida(concrete block exterior walls with interior wood stud walls) in the 1970s.She has discussed rewiring with 4 other Electricans.Her mind set was to pull out all the Al and replace it with Cu.I asked if she was having problems with the Al and her reply was that she did not want to pay to "maintain" a house with Al wire,like going around every few years and tighting all the screws on the recpt,switches etc.I asked for an example of problems that she had had.She immediately pointed to the TV and blamed the intermittent operation on Al wiring.I proved to her in the next 2 minutes that the problem was the TV.It appears that the original installer did not use an oxidation reducer paste but all else loked OK.
I have worked on houses with Al wiring but was never asked to do a rewire.
What are some of the other issues with Al wiring?
