Is it a pure copper wire or copper clad aluminium (CCA)?

I installed the wire last summer. Used 98+ ft from a 100 ft roll, ceiling mounted Bose 901's. Sound is exceptional. Cable was very flexible and certainly appeared to be all copper. Both positive and negative cable lines are copper colored but the positive is given a continuous red stripe. I have some similar cable used in an auto installation (14 or 16 GA) that is also all copper colored and very flexible. The positive line is identified with repetitive + + + +. It is pure copper as best I can tell.

This is pure copper wire and it works great. No aluminum at all. Just braided copper.

I believe that it is indeed copper. When I put my home theater system together, the strands looked like copper to me.

I can't give you a definitive answer, but I think that the copper is covered by the stainless steel. I LOVE it and it has worked perfectly. My plumber who installed it said he installed one that was very similar, but 100% more expensive. He did not find anything that was harmful or he wouldn't have installed it if it weren't up to code. Hope this helps.

Hello Hoosierdoodles,The cable has both aluminum and copper conductors. It's about 85-90% aluminum and the rest is copper.Thank you for your question.Taylor W.VIVO

I'd go with 12ga. There's a plastic tube in the middle of each conductor so actual copper is probably 14ga.

It is all copper. Aluminum would be completely unsuitable... This is very good speaker wire and I am very satisfied with it.....

Yes, it appears to be. I've been using it for over a year now, and I have every reason to believe it is 100% copper.

Yes, this is copper hook-up wire. That means the wire is tinned - solid copper with a thin outer layer of tin, before the outer layer of insulation. It is not a copper alloy as Phillip stated.

I received cables that were copper coated aluminum. Apparently after getting good reviews they started to get cheap like the other sets they sell.

Yes it is solid copper. It can be used for dish network, however, it is not officially dish network approved.

It is copper and it is twisted. Also use the 12 gauge if you are running longer distances.

The way it feels and flexes, I would say it's copper. I really don't know but it says that it's no. 8 wire so I think it is. Can't the manufacturer be asked? I really don't know for sure. If you find out, can you tell me please? It works fine on my welding machine.

30A, we've run them up to 17A, giving a safety factor. They are copper with silver plating, perfect for REDUCING internal resistance and I^2 R loss.

No, just pure copper.....but if you're buying it for Ayurvedic purposes, that's all you want. Once you get used to the pureness of a noncontaminatory metal, anything with a liner is just nasty ;-)....but that's just my two coppers.

When I purchased this wire, I read a lot of reviews, and some of these reviews contained claims that the wire was copper plated aluminum. I got this wire from SatMaximum. They claimed it to be copper in the ad, but I see that they must have started over with the ad, because there are only 3 reviews on this new ad, which makes no claim either way on its composition. Overall I am happy with the product, although it does appear to have a silvery core, which may be aluminum...

While I did not cut it open to verify, I am sure this is NOT copper. If it was, the manufacturers would have stated that fact somewhere on the label and description. They do not state the type of metal used for the wires anywhere. Many use copper coated aluminum wire.

The 18/2 appears to be CCA, because I scraped on it with a knife, and the copper came off, exposing the aluminum. The marking on the cable and on the box does not state this. It only says 18/2 power cable. The RG59 is copper clad steel.
