You might be right about the use of higher copper content (which would result in higher conductivity), but I'm not sure. My company manufactures copper alloy strip for use in electrical and electronic connectors. For wall receptacles of any classification, I believe that 70/30 brass is always used. High-performance (high conductivity, high strength) copper alloys tend to be used primarily in electronic connectors or electrical connectors in harsh environments (such as automotive under-the-hood). For plug prongs and their female counterparts (sorry about the terminology but that's just the way it is), conductivity is compromised by the need for spring retention for insertion/withdrawal forces. 70/30 brass has a conductivity rating of only 25%, versus 100% or ETP or OFHC copper. Perhaps the only difference in grades is the gauge of brass used.
