He was pretty specific that his pitch was just for lugs and larger wire. The talk about Al romex was just answering a question.
He did pass out samples of the old, bad 1350 alloy and the new AA8030. I can see it is a lot better. When you bend the 1350, it tends to kink and bend in one spot. The 8030 takes on a long arc.
The 1350 is really only designed for aerial lines, not something you will be bending a lot. It is pretty stiff.
The 1350 stuff they used in romex was annealed so it would bend easier but they still did not address the kinking problem. The "aluminum problem" was because they use steel screws in non-co/alr devices and the expansion rate is vastly different. The co/alr device has a screw that matched aluminum better, along with being bigger and I think there is some "bite" on the mating surface to grab the aluminum.
I still would not use it. We agree there.
