copper clad aluminum wire

Copper clad aluminum wire ,CCA\CCAM\TCCAM wire Copper clad aluminum wire diameter of wire: 0.1mm-3.0mm

We are leading manufacture and supplier of copper clad aluminum wire (CCA), copper clad aluminum magnesium alloy wire (CCAM), tin-plating copper clad aluminum wire (TCCA). The surface is bright and smooth without any default. Therefore the copper clad aluminum wire is featured of both the small density of aluminum and the good conductivity of copper. This kind of double-metal compound wire is used as the conductor in coaxial cables, high-frequency signal transmission cables, control cables, electromagnetic wire and special enameled wire and many other fields. It not only has high signal transmission property, but also has characteristics such as low weight and low production cost.

1) Copper clad aluminum wire specifications and expression: Copper clad aluminum wire  by volume (Copper volume percentage of the total volume of the copper wire) is divided into two type : 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 clad aluminum 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 clad aluminum 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). Copper clad aluminum wire 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 copper clad aluminum wire  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 copper clad aluminum wire . So it is the preferred materials. It can be divided to two species by mechanical properties.  3)Copper clad aluminum wire  advantages : Copper clad aluminum 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 clad aluminum wire  is 2.6 times than the pure copper's length 2.6 : 1. This will greatly reduce the cost of production lines. And copper clad aluminum wire  can reduce the raw-materials largely for the buyer. Compared with the pure copper, copper clad aluminum 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.  copper clad aluminum wire is more malleable than copper, and doesn't bear insulating oxide like Aluminium. So copper clad aluminum wire is easier to take into processing and have better conductive.  copper clad aluminum 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.
