Copper clad aluminum wire/cca wire

Copper clad aluminum wire /cca wire is the new products replacing the previous generation, and widely recommended by the country

Copper clad aluminum wire is the new products replacing the previous generation, widely recommended by the country, taking the international advanced craftwork of cover welding.          It is the bimetal wire that makes the metallurgy combination of copper layer and aluminum-core wire, through the way of cover the copper layer on the aluminum-core wire.and also realize the copper layer spread to circumference and portrait way with balanced concentricity.

  

The advantages of Copper clad aluminum wire:

 1. DC Resistivity: the dc resistivity of copper clad aluminum wire is just 1.5 times than that of pure copper wire, and as the resistive rate is the same, copper clad aluminum wire’s weight is about half of the pure copper wire, so according to the ‘skin effect’, on the point of or above the 5MHZ, the resistive rate is the same with pure cooper wire.

2. Well welded: cooper clad aluminum wire has the good welding capability as the pure cooper wire for its surface covered with a layer of cooper.

3. With light weight: the weight percentage between the cooper clad aluminum wire and the pure cooper wire is just 37% to 40%, so under the circumstance of the same weight and wire size, its length is 2.5 to 2.7 times that pure cooper wire, which has lower the production cost.  

4. Soft quality of copper clad aluminum wire and easily processed .

The physical characteristic of copper clad aluminum wire:

Product spec	Copper layer (volume ratio%)	Copper layer (quality ratio%)	Density (g/cm3)	DC Resistivity (Ωmm2/m)	DC Conductivity (%IACS)
CCA-10%	8-13	27	3.32	0.02743	63
CCA-15%	13-17	37	3.63	0.02676	65
