High Quality Copper Clad Aluminum CCA Wire for Electronic Components and Power Transmission

We're looking at CCA wire in diameters from 0.07mm up to 3mm, with copper content options at 10%, 15%, or 20% by volume—basically, you choose how much conductivity you need versus how light you want it. It's pretty much always in demand for coaxial cables and power transmission because the copper cladding gives you that surfce conductivity, and the aluminun core keeps weight down.

Most buyers go with the annealed 15A variant for electronic components where flexibility matters, but hard drawn is better when you need higher tensile strength at 110-207 MPa. It's not suited for high-frequency signal lines where pure copper is still the standard, so know your applicaion before ordering. Resistivity sits at 0.0259 to 0.0274 Ω·mm²/m at 20°C, which is usually good enough for general power work.

Elongation ranges from 1% to 15%, and that number matters if you're doing any crimping or bending post-installation. One thing we get asked a lot is about density—it's 3.32 to 3.94 g/cm³ depending on the copper content, so don't assume all spools weigh the same. The MOQ is typically 100kg or so, but our company can do smaller runs for sample testing.

ISO9001 and CE certified, plus RoHS compliant, so you're covered for most import requrement. We usually have stock on the 0.5mm and 1mm diameters in annealed state, but if you need hard drawn or an odd size like 0.07mm, confirm lead time—sometimes it's 20 days or so. Also, we ship with COAs for every batch, no extra charge.
