Copper Clad Aluminum Wire, Standard : ASTM

Copper Clad Aluminum wire (CCA wire)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.
Feature:
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

Application:
In high frequency signal transmission field, it is applied to:

• Standard Material of Conductor in CATV Coaxial Cable;
• 50 Ohm Radio Frequency Aerial;
• Leaky Cable;
• Soft Coaxial Radio Frequency Cable;
• Data Cable

In power transmission field, it can be applied to:

• Stranded wire;
• Power Cable;
• Control Cable;
• Automotive cable;
• Building distribution wire;
• Busbar;
• Radio Frequency shielding;

In special electromagnetic wire, it can be applied to:

• Coils in motor and fans, mahjong machine, Loudspeakers
• Voice coils (e.g. in Headphone, Headset, ...)
• Windings
