Clad metals are two distinct metals or alloys that are metallurgically bonded together so that the optimum combination of functional properties is achieved. Copper Clad Aluminum (CCA) is an electrical conductor with a sleeve of copper bonded to a solid aluminum core. The composite wire is uniquely suited to the electrical applications where weight to 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.
