Copper Clad Aluminum Wire(CCA)

Copper Clad Aluminum Wire (CCA) Diameter: 0.10- 4.0mm Copper Clad Aluminum wire Standard: SJ T 11223-2000,ASTM B 566-93

1) Copper clad aluminum wire specifications and expression: Copper wire by volume (Copper volume percentage of the total volume of the copper wire) is divided into two categories : Copper volume ratio in the range of 8 to 12% level is 10% grade (credited to 10) Copper volume ratio within the 13-17% level is 15% grade.(credited 10 to 15). Copper wire is also divided into two categories : hardware and software, can be pull to different diameters according to request. It called H when it is hard after finishing pulling and un-annealing. However it called A.So copper wire can be grouped into four categories : 10H, 10A,15H,15A. Drawing into different types of copper wire also.Copper wire is expressed by the code of CCA (Copper Clad Aluminum). specifications expression: For example : For 2.77mm in diameter, the volume ratio of 15% of the copper layer of soft copper wire. Marking its specifications : CCA-15A-2.77 2) Copper clad aluminum wire Physical properties : Copper clad Aluminum wire is a kind of double metal wire which is formed by Aluminium and copper outside neatly. And it can be divided to 10% and 15% by the volume. DR resistivity at 20°C were≤ 0.02743 Ω mm2/m and ≤ 0.02676 Ω mm2/m. 3.32g/mm3 and 3.63g/mm3are nominal density. We can adopt the same technology and processing on the wire copper. So it is the preferred materials. It can be divided to two species by mechanical properties.  3)Copper clad aluminum wire  advantages : Copper wire is produced by international advanced welding technology. The copper adopts the pure copper with 99.97% above density, copper layer is of high density, and good conductivity; Copper layer and Aluminium core combined well and have good concentric degree.  Under the same conditions as in weight and diameter, the length of copper wire is 2.6 times than the pure copper's length 2.6 : 1. This will greatly reduce the cost of production lines. And it can reduce the raw-materials largely for the buyer. Compared with the pure copper, copper wire is of no value for the thieves.Because the separation between the copper clad Aluminium and Alumium layer is almost impossible. Therefore, it can add security.  It is more malleable than copper, and doesn't bear insulating oxide like Aluminium. So it's easier to take into processing and have better conductive.  Copper wire has light weight and it is convenient to transport and install. so it can reduce the labor4)Copper clad aluminum wire  Application areas : 1. High-frequency signal transmission : Flexible RF coaxial cable; Leaky in inner cable conductor; Network cable inner conductor; Micro coaxial inner conductor; coaxial cable conductor material within the first 50 Ω RF cables. Flexible RF coaxial cable inner conductor; 2. Electricity Transmission : Wire material; Fuse; Power cable conductor; Bush conductor wiring construction materials;3. Bus conductor materials, etc.: Cars, locomotives cable conductor; Computer cables, control cables and other data cables with conductors 4.
