【ALUMINIUM CHINA CO.,LTD.】 Copper clad aluminum wire adopts advanced cladding welding manufacturing technology, which concentrically covers high-quality copper tape on the outer surface of aluminum rods or steel wire cores, and forms the copper layer and the core wire. Strong metallurgical bonds between atoms. Combining two different metallic materials into an integral whole, drawing and annealing can be performed like processing a single wire. Copper and aluminum are reduced in proportion to the drawing process, and the volume ratio of the copper layer is kept relatively constant. change.

First, the performance of copper clad aluminum:

1. Conductive performance: Since the high-frequency signal has the “skin effect” feature, copper-clad aluminum and copper-clad steel wires have the same conductivity as pure copper wires when transmitting high-frequency signals (greater than 5 MHz).

2, the unique composite properties: copper clad aluminum wire at the same time with the conductivity of copper and aluminum density of the composite characteristics; and copper clad steel wire is the copper conductivity and the high strength of steel together. Tin-plated copper-clad steel wire plays a role of tin solderability and sulfidation resistance; silver-plated copper-clad steel wire has improved conductivity, thermal conductivity, increased corrosion resistance, and oxidation resistance.

Second, the application of copper clad aluminum.

1. Applications in electrical and electronic applications: coaxial cable inner conductor materials for cable TV subscriber lines and near-home cables; conductors of computer cable LANs, access network cables, and field cable inner conductor materials for parallel dual-core telephone subscriber communication lines; Connectors for electronic components; overhead lines for power transmission and telephone lines;

2. Application of electrical power: Overhead lines of catenary overhead lines of electrified railways and rail transit lines; textile shielded cables of power cables; grounding of electric power industry;

3, medical: the connection line conductor material of medical equipment and equipment;

4. Aerospace: Cables and cables for aviation and spacecraft;

5, high temperature electronic wire conductor material; high temperature RF cable core; high frequency signal transmission;

6. Other applications: internal conductors for special cables for automobiles and motorcycles; conductor materials for construction fabrics; conductive materials such as busbars; fuses;
