Application

Copper-clad aluminum wire for high-frequency coaxial/RF applications (RF antennas, CATV distribution cables), voice coils in speakers/headphones, control signal cables, and lightweight building wiring where weight reduction is critical. Aluminum core with 10-15% copper cladding. 60-70% IACS conductivity of pure copper.

Core Strengths

High-frequency coaxial cables need lighter weight without sacrificing signal integrity. Our CCA delivers the skin effect advantages of copper with the weight savings of aluminum (≈60% lighter). 10-15% copper cladding ensures reliable soldering. Cost-effective for CATV and RF applications.

Standard

GB/T29197, ASTM B 566

Construction

☉〉 Core: Aluminum (EC grade)

☉〉 Cladding: Copper metallurgically bonded to aluminum core

☉〉 Types: Solid, stranded, or flexible

Features

☉〉 Lighter than solid copper (about 1/3 the weight)

☉〉 Lower cost than pure copper with acceptable conductivity (≈65% IACS typical)

☉〉 Good corrosion resistance from copper outer layer

☉〉 Suitable for coaxial cables, audio wires, and power transmission where weight reduction is needed
