Copper Clad Aluminum Wire
Over the last years in many markets there has been increasing interest in copper clad aluminum (CCA) wires as a possible way of reducing material costs in certain types of cables. CCA consists of copper cladding surrounding an aluminum core. The most common grade of CCA is 10% CCA, that it means 10% copper by volume. Only 5% of the radial thickness is copper and the rest is aluminum. It contains approximately 43% copper by weight, since the copper is a much denser metal than aluminum. 10% CCA has an overall conductivity of 65% IACS, i.e. 65% of the conductivity of an all copper conductor at the same cross-section, but its average density is only 37% of copper.
Electro-Plating Technology:
Name | Diameter | Copper Content | Conductivity (IACS) | Tensile Strength | Elongation | Density |
CCA | 0.15~6.0 mm | Below 10% | 60%~62% | 120 Mpa | ≥12% | 2.9 g/cm³ |
Copper Cladding Technology:
