cooper clad aluminum

High conductivity Good corrosion resistance Excellent elongation Smooth surface Low cost

CCA Wire, Copper clad aluminum is a composite wire consisting of an aluminum core clad with copper.Even though the material is 65 - 75% aluminum, the wire has high frequency electrical properties equal to solid copper. The advanced coated welding manufacturing technology integrate the cooper cover and the aluminum pole to  a whole and then pull out and annealing processing could be uesd like a single metal.

The  "hasten skin effect" make the copper cald aluminium wire has the same electric properties at a high  frequency signal (more than 5 MHz).

Conductivity coefficient           0.02616

Electrical Conductivity                 66%

Tensile strength                       128Mpa

Elongation                               ≥15%

Density                         3.32g/cm3 – 3.63g/cm3

Range                              0.15mm – 3.00mm

CCA wire:

1) Diameter: 0.15 - 3.00mm

3) It is divided into 25% and 8% two kinds according to volume scale of copper layer

4) The DC resistivity at temperature of 20°C is less than 0.02676Ω.mm²/m

5) Its nominal density is 3.32g/cm³ - 3.63g/cm³, it is 35 - 37% of pure copper wire

6) Under the same weight, its length is 2.5 - 2.7 times that of pure copper wire

7) It has become the most common wire used in CATV and other high-frequency conduct cable

8) It is a bimetallic wire with a copper cladding concentrically covering an aluminum core, integrating the beneficial properties of the wonderful conductivity of copper and the light-weight of aluminum.

9) It can be scientifically processed into bare wire , and it is the best material for coaxial cable, computer cable,

 telephone cable and shielding cable.

10) The processing method is similar to that of copper wire during cable manufacture.
