Copper Aluminum Atomic Bonding wire is a conductor composed of an inner aluminum core and outer copper cladding. The primary applications involve of this conductor revolve around weight reduction requirements. These applications include high-quality coils, such as the voice coils in headphones, portable loudspeakers, or mobile coils; high frequency coaxial applications; such as RF antennas; CATV distribution cables; and power cables.

  • Lighter than pure copper
  • Higher conductivity than pure aluminum
  • Higher strength than aluminum
  • Less expensive than a pure copper wire
  • Typically produced as a 10% or 15% by copper volume
  • Better solderability than aluminum, due to oxide
  • layer which prevents solder adhesion when soldering
     bare aluminum
