Copper-clad aluminium (CCA) wire is available with 10% or 15% copper cladding over an aluminium wire core. Copper-clad aluminium wire offers the inherent characteristics of aluminium while the copper cladding provides greater conduction of current and the ease of soldering of copper.
Copper-clad aluminium
| Alloy | Chemical composition | Ultimate tensile strength | Electrical conductivity IACS 20°C (68°F) | Electrical resistivity | Density | Coefficient of thermal expansion |
|---|---|---|---|---|---|---|
| 10%CCA | 10% Copper by volume | 82.7 Mpa (12.0 ksi) | 62.854 | 2.74 Ohms cm 10-6 (16.5 Ohms cir-mil/ft) | 3.32g/cc (0.12 lb/in) | 22.9 µm/m-°C (12.7 µin/in-°F) |
| 15%CCA | 15% Copper by volume | 117 Mpa (17.0 ksi) | 64.416 | 2.67 Ohms cm 10-6 (16.1 Ohms cir-mil/ft) | 3.63g/cc (0.131 lb/in) | 22.9 µm/m-°C (12.7 |
ADVANTAGES:
• The bimetallic wire integrates the beneficial properties of good conductivity of copper & light weight of aluminium in a single wire called CCA wire
• CCA wire can be easily processed to fine or flat wire
• The density of CCA is about 37-40 % of that of copper. Its length is 2.45 – 2.65 times of copper in the same weight & diameter. These factors reduce the raw material cost for cable manufacturers.
• Environment friendly, CCA saves the copper resources & its production is a nonpolluting process.
• CCA is easy to transport & install as its light weight.
