[QUOTE="sundownz, post: 7086352, member: 549523"] Even for your alternate example... lets examine: 4-layer copper / 63.5mm former / 45mm WW / 7.01 ohm = 0.48mm diameter wire / ~113 grams / 67.74 mm OD Now using the largest typically available CCAW wire : 4-layer CCAW / 63.5mm former / 45mm WW / 1.46 ohm = 0.90mm diameter wire / 66.8 grams / 70.88 mm OD The coil is vastly different so not even comparable at all... to get somewhat comparable in mass at a given WW you would have to get into 8-layer or more flat aluminum coils (like 12-layers). I like a good copper coil as well -- I use them in my SA series and Z v.2 series. It really is going to come down to the overall design -- one material isn't simply superior flat out, IMO. I use both materials in design based on my goals. [/QUOTE]
