Description:

Copper-clad aluminum CCA wire refers to a new conductor material formed by coating a thin copper layer on the aluminum core wire and making the atomic bonds on the interface between copper and aluminum produce metallurgical bonding

It not only takes advantage of the excellent electrical conductivity of copper and the light weight of aluminum, but also overcomes the disadvantages of easy oxidation of aluminum, high contact resistance, and difficult welding of joints, and greatly saves the scarce copper resources in my country and reduces the cost of conductors.

Mainly used in coaxial cable inner conductor, audio and video cable conductor, shielded braided soft conductor or enamelled winding wire base material, etc.

Types of copper clad aluminum CCA wire

Copper clad aluminum wires are divided into two grades of 10% and 15% according to the volume ratio of copper layer, divided into soft state (Annealed, Abbreviated as A) and hard state (Hard, Abbreviated as H), the model is CCA;

Copper-clad aluminum alloy wire is divided into three grades according to the copper layer volume ratio: 10%, 15% and 20%, all of which are soft (Annealed), and the model is CCAA;

Tinned copper-clad aluminum alloy wire is also divided into three grades of 10%, 15% and 20% according to the copper layer volume ratio, all of which are soft (Annealed), and the model is CCAAT.

Features of copper clad aluminum CCA wire

Lightweight: The core of copper-clad aluminum wire is aluminum, which is lighter than pure copper wire. This makes copper-clad aluminum wire an advantage in applications where overall weight reduction is required, such as in the automotive and aerospace sectors.

Low cost: Due to the relatively low price of aluminum, the cost of copper-clad aluminum wire is lower than that of pure copper wire. This makes copper-clad aluminum wire an economical choice, especially for applications where large quantities of wire are used, such as construction, power transmission, and communications.

Electrical conductivity: Copper-clad aluminum wire has a certain difference in electrical conductivity compared to pure copper wire. Due to the lower electrical conductivity of aluminum, the resistance of copper clad aluminum wire will be slightly higher than that of pure copper wire of the same size. Therefore, in some applications that require high electrical conductivity, the limitations of copper-clad aluminum wires may need to be considered.

Corrosion resistance: The copper cladding of the copper clad aluminum wire provides good corrosion resistance and can resist some common corrosive media. This makes copper clad aluminum wire more reliable in some specific environments, such as outdoors and humid environments.

Machinability: Copper-clad aluminum wire has good machinability and can be cut, stripped and connected using conventional wire processing techniques. This makes copper clad aluminum wire easy to install and maintain.

Although copper-clad aluminum wire has some advantages, the selection of copper-clad aluminum wire should be evaluated according to the requirements and limitations of specific applications. For some demanding applications, such as high current loads or applications requiring lower resistance, it may be necessary to use pure copper wire.

Uses of copper clad aluminum CCA wire

Power transmission: Copper-clad aluminum wire can be used to transmit power, including low-voltage and medium-voltage power transmission systems. They can be used in electrical wiring of buildings, power distribution networks, and for industrial and commercial purposes.

Communication systems: Copper-clad aluminum CCA wires are often used in telephone lines, network cables, and other communication systems. They provide reliable signal tranmission and data transmission capabilities.

Automotive industry: Copper-clad aluminum wires are widely used in automotive electrical systems. They are used in the manufacture of wires and cables for vehicles, such as battery wires, engine wiring harnesses, light circuits, etc.

Electronic equipment: Copper-clad aluminum wire can be used for internal wiring and connection of electronic equipment. They are widely used in televisions, audio equipment, computers and other consumer electronics.

Aerospace: Copper-clad aluminum wires have important applications in aerospace due to their lightweight properties. Copper-clad aluminum wire can be used in aircraft electrical systems, communication equipment, and internal connections of spacecraft.

It should be noted that the specific application depends on the specification of the copper clad aluminum wire, the current capacity requirement, and the technical requirements of the specific project. When selecting and using copper-clad aluminum wire, it should be evaluated and confirmed according to the application environment and relevant standards.
