Copper Clad Aluminum Wire

CCA wire has the characteristics of both copper wire & aluminium wire low density from good conductor from copper wire.

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.

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.
