Our cable is Copper...REAL COPPER but watch out for other "CCA Cable" as CCA Means Copper Clad Aluminum so you'd be using Aluminum which is a poor conductor compared to this pure copper cable! You have to use larger sizes of aluminum CCA cable, approximately 2 sizes larger to get close to the same power delivery as real copper cable! If you care about maximum power use our cable!

Suitable Uses:
