Copper-Clad Aluminum Conductors
Copper-clad aluminum combines an aluminum core with copper cladding. Choose round wire, flat wire, strip or foil for your conductor design, then compare weight and resistance at the dimensions the application requires. Copper content, temper and connections are part of that decision.

Select the required form to review its dimensions and specification. Wire, strip and foil have separate requirements; a family name does not make their specifications interchangeable.

At the same dimensions, CCA is lighter than copper and has lower conductivity. A design that must match copper's resistance may need a larger cross-section, so the useful comparison is the finished conductor at the required electrical duty.
Copper content, core material, dimensions and temper determine the specification. Copper content must state its basis: mass, volume or cross-sectional area.
Terminations, temperature rise and corrosion exposure are part of the material decision. Test the proposed conductor and its connections in the intended assembly before changing an approved copper design. Where the governing specification requires copper, the material change also needs approval.
Choose the round-wire, flat-wire, strip or foil page for that form's specification.
