Enameled Copper Clad Aluminum Wire

ECCA – Conductor

Copper Clad Aluminum (CCA) is a clad bi-metal utilizing electrical conductor grade aluminum as its core and oxygen free copper for its outer layer. The cladding process creates a permanent continuous weld between the two metals. The composite wire is uniquely suited to electrical applications where weight and conductivity issues are critical. The copper makes up either 10% or 15% of the cross sectional area of the wire and assures excellent solderability. AC conductivity at frequencies greater than 5MHz is equal to solid copper. CCA is manufactured in accordance with the requirements of ASTM B-566. Film Insulations are available on CCA. See the magnet wire insulation guide for enamel options.

Structure and Composition

Core:
Aluminum: The core of the wire is made from aluminum, which is lighter and less expensive than copper.
Cladding:
Copper Cladding: A thin layer of copper is clad around the aluminum core. This copper layer is typically applied through electroplating or metallurgical bonding processes.
Insulation:
Enamel Coating: The wire is coated with an insulating layer of enamel. This enamel provides electrical insulation, protecting the wire from short circuits and environmental factors like moisture and chemicals.
