Once upon a time on a similar thread these words came off my finger tips.
I purchased single outlet Hubbell 6361's less resonance I believe, all brass and copper save for some external mounting and one terminal screw which I replaced for brass. I had these triple cyro'd and ordered single gang stainless [virtually non magnetic] steel mounting plates. $6 for each of the outlets $6 for the plates and 20 bucks for the cryo for the 10 I had treated. In the past I found some name brand Gucci priced duplex's that were suppose to be entirely non ferrous, non magnetic. Guess what with the aid of a neodymium magnet I made the internal parts hop around so they were not as written non magnetic. I sent all these back. Some complain that copper based alloys may oxidize and wear more quickly the single plugs are always full and never unplugged. All my power cords use copper connectors as well so I may never see or hear the affects of galvanic corrosion. I believe in the synergy of using the same materials.Tom
