Are these cables made of copper or aluminum?

These cables are made of copper-coated aluminum wire. No question about it. What is worse, I think, is that the crimps in the clamp handles have no strain reliefs. Since aluminum does not handle repeated flexing, I would expect to see eventual failures at the crimps. I have no doubt this product will perform well with limited use, but I would not buy it if you expect to use it frequently.

The cables are multi-strand copper conductors, and appear to be copper or copper clad jaws. The spring mechanism for the jaws uses a steel spring.

Coleman's website does indeed say copper equivalent for "cable gauge." It also says CCA for "conductor stranding," which stands for copper clad aluminum. It is an aluminum wire with a copper outer layer.

Any booster cables under $100 are copper coated aluminum, it's that simple.

Coleman's website says they are copper equivalent .....whatever that means?

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

Copper clad aluminum. They did not make it clear in description but it works fine so far. I know because I chopped it down into two sections of cable.

It's copper coated aluminum. Bad miss leading advertisement. It's ok for the short run, but I wouldn't recommend for the performance use.

Mine were aluminum, and very well built. You should note the seller so that others can avoid being ripped off.

I don't know the copper by volume specifications but I would say that the cable did not have the appearance of aluminum. I bought this product for my house and have typical cable lengths around 40 ft. Applications include Cisco VOIP with video service, Skype, Dropbox and WebEx. I can't see any difference in performance from this cable to the product I purchase at Lowes and Home Depot. I've run http://www.speedtest.net/ and got expected results.

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.

Copper.....I had to change the male connector , the only reason I know for sure....Your getting your money's worth on this cord.

I am not completely sure but I would say aluminum. They can bend very easily.

As of December 2014 the Amazon description states: "Material: CCA - Copper Clad Aluminum (The top of the cable where the data transfers is copper and the base metal is aluminum)".

The wire that I received was copper. This is a good question and I didn't think to ask it until after I placed my order. But the wire is copper and a good quality.

They appear to be copper through & through. After a year's use we are still very happy with them.

Everything but the internal cable is aluminum. The cables are to prevent the steps from falling into the water when adjusting the level.

Hey Wareren, .. ok, I took a knife too one of my connectors; though it all looks like copper, I was however, able to cut a surface layer off identifying aluminum. Weight also doesn't line up with what would the weight of 25' of copper cables. I will note, they have worked fine for the occasional use that I had need of them. I still really like the quality connectors, all the rubber, and the carrying case is of better quality than I expected. Personally at this price point & again, for what I'm using them for, I would buy again. Note: Though these are called "commercial duty", I would not buy them for commercial use!
