Copper vs copper clad aluminum. Does the flexibility really matter?
Shouldn't the conductivity be compared and not the flexibility? I did a little bit of my own research while you guys debated over copper vs copper clad...
COPPER-VERSUS-ALUMINUM CONDUCTORS
Although silver is the best conductor, its cost limits its use to special circuits. Silver is used where a substance with high conductivity or low resistivity is needed.
The two most commonly used conductors are copper and aluminum. Each has positive and negative characteristics that affect its use under varying circumstances.
CHARACTERISTICS.........................................COPPER......ALUMINUM
Tensile strength (lb/in2)...................................55,000...........25,000
Tensile strength for same conductivity (lb)..........55,000...........40,000
Weight for same conductivity (lb)..........................100.................48
Cross section for same conductivity (C.M.)..............100...............160
Specific resistance (W/mil ft)...............................10.6.................17
Copper has a higher conductivity than aluminum. It is more ductile (can be drawn out). Copper has relatively high tensile strength (the greatest stress a substance can bear along its length without tearing apart). It can also be easily soldered. However, copper is more expensive and heavier than aluminum.
Granted this is copper vs aluminum. But put a copper coating over the aluminum and you have the best of both worlds. Lightweight aluminum core with the high conductivity coating of the copper coating. Granted it's not solid copper or solid aluminum so conductivity and weight will most likely be somewhere between those numbers posted above.
Not to mention there are varying degrees of quality of copper and aluminum. And there for even more quality possibilities of copper clad aluminum wire.
My opinion is this.....
To each their own. If someone chooses to use cca so be it. It's their choice and it's cheaper. After all maybe you got a bad batch of cca wire.
Sorry, but I started this thread to try and learn from people who know more about stereo equipment than I do. And did not mean for it to end up being a pissing contest on which wire is better.
With that said. I have now entered my 2¢ worth.
Now on to bigger and better things. I just received my new head unit. It's a
JVC KW-XG700. I know some of you are going to say JVC????? why????? well.... It's one of the few Double Din styles that I liked. Most of the others looked like crap in my opinion.
