Automotive aluminum wires

An aluminum wire was developed to reduce the soaring copper amount and to reduce a wire self weight by 30 to 50%.

As the pure aluminum has disadvantage in mechanical strength in comparison with copper, so an aluminum alloy was adopted. By improving flexibility and bending property of the aluminum, generally stiff, the aluminum alloy suitable for the automotive conductor was developed and adopted. (Patent applied for)

  • Weight reduction: by 30 to 50%.
  • Cost: Equal to or less than the conventional copper wire.
  • Furukawa original aluminum alloy⇒ The aluminum alloy suitable for automotive wire.
