Product Process:

Advanced cladding welding technology. It consists of an aluminum core wire and a tightly coated outer copper layer to form a double metal wire.

The difference between copper clad aluminum wire and pure copper wire

Compared with pure copper wire, copper clad aluminum wire has the following characteristics:

1. Saving metal copper, greatly reducing production costs. At the same time, copper-clad aluminum is used instead of pure copper, which saves rare resources.

2. Improve the stability and reliability of coaxial cable signal transmission. Coaxial cable is usually made of aluminum as the outer conductor. Because the expansion coefficient of copper clad aluminum wire is closer to aluminum than pure copper, it reduces the connection failure caused by the temperature change and the expansion of the inner and outer conductors of the cable. .

3. The copper clad aluminum wire is light in weight and small in density, easy to transport and install, and greatly reduces the labor intensity in the network construction. The mass ratio of copper to aluminum is 3.3..1, and the density of copper-clad aluminum wire is only 37.3% to 40.8% of the density of pure copper. Under the same diameter, the length of 1 ton of copper-clad aluminum wire is 1.7 to 2.45 times of the length of pure copper wire of the same quality. The structural characteristics of the copper clad aluminum wire are: the outer layer is pure copper or copper, and the thickness thereof is small, and the core is aluminum metal. The frequency of cable TV signals and mobile communication signals is very high, generally around 50-800 MHz. Due to the "skin effect", the high-frequency current is mainly concentrated on the surface layer of the conductor, and the aluminium itself has good electrical conductivity, so The copper clad aluminum composite material can replace the pure copper or copper to ensure the transmission efficiency of the cable. The price of aluminum is lower than that of copper, and its density is less than one-third of that of copper. Therefore, the weight per unit length of the wire can be greatly reduced, which is beneficial to the installation and construction of the cable.

Copper clad aluminum wire application field:

1. High-frequency signal transmission flexible coaxial RF cable material; inner conductor material of leaky cable; inner conductor material of network cable; inner conductor material of micro coaxial cable; inner conductor material of cable coaxial cable; 50Ω RF cable, flexible RF Coaxial cable inner conductor material;

2. Power transmission strand material, fuse material, power cable conductor material, construction wire conductor material, bus bar and other conductor materials, automotive and locomotive special cable conductor materials, computer cables, control cables and other data cable inner conductor materials;

3, other areas: audio, video conductor materials; power line conductor materials; computer peripheral lines, computer cable conductor materials. https://www.acreemetal.com/plate...clad-aluminium-wire.html
