COPPER CLAD ALUMINUM - CCA15%

General Description

ELEKTRISOLA copper clad aluminum wire (CCAW) is a bimetallic compound of an aluminum core with a concentric copper cladding. This material combination provides a wire with optimum properties of both metals. The aluminum core reduces the weight of the CCAW to almost that of pure aluminum wire. Furthermore the copper cladding increases the conductivity and allows the same soldering process as it is used for copper wire. The properties provide a conductor optimal for high quality coils used in headphones, headsets, loudspeakers and many other applications where coil weight reduction is desired.
Copper clad aluminum wires are available in diameters from 0.025mm to 0.500mm (AWG 50 - 24) with all insulation and self-bonding enamel types. The percentage of copper per volume can be choosen between 10% and 15%, whereas the 15% copper cladding is recommended for diameters below (AWG 38) 0.100mm and the 10% for diameters above. Bare wire and claddings with other percentages of copper are available upon request.
