Copper Clad Aluminum Wire

Model: CCA
Capacity:500 tons/m
Standard: GBT 29197-2012 ASTM B566-04A
  • Description
Copper Clad Aluminum is an electrical conductor which has an outer sleeve of copper metallurgically bonded to a solid aluminum core. The combination of these two metals make it uniquely suited to many electrical applications
Compared to copper conductors:
Higher Flexibility due to lower elastic modulus
63% material weight reduction due to lower specific gravity of CCA over regular copper
Compared to aluminum conductors:
Better corrosion resistance than aluminum due to copper layer
Lower resistance due to high electric conductivity of copper
Better Solderability
Higher strength than aluminum
