I could be wrong about this, but judging by the debacle during the 70's
where a lot of aluminum wiring got installed in a lot of homes--and later
caused at least a few fires--I'd at least be cautious.
That was mostly hype stirred up by Jeraldo Riviera. Back when he
was still caucasion.
The real problem with aluminum wiring was three fold. 1. For a
given current ration, the aluminum wire has to be bigger than
copper. 2. Special terminations (screw and or compression type)
marked CuAl shoud be used along with a gel like "No-Ox" to protect
the connection 3. Proper torque on the fastenings is manditory.
Given the special requirements and the attitude of most workers
that "I know what I'm doing" of course it was a disaster.
I've also seen several places in my old houses where iron piping
was screwed directly into brass fittings. [ snip ] When finally
I got down to it, there was practically nothing of the threaded
end left, although the rest of the pipe was in good condition.
This is more the fault of the iron pipe. Not the bronze/brass
fittings. When you thread the end of a pipe, you remove the
galvanized coating. Exposed metal pipe = weak spot.
