Copper-clad aluminum wire is a new type of product that has been vigorously promoted by the country many years ago, and adopts internationally advanced welding technology. Products are divided into soft state (type A) and hard state (type H). According to the volume ratio of copper layer, it is divided into two kinds of 10% and 15%. Its nominal density is 3.32g / cm3 and 3.63g / cm3. It is (37-40)% of pure copper wire, and the length ratio of the same specification and the same weight is 1: 2.45.

The technical indicators of the copper clad aluminum wires of Sanle's leading products have reached the national electronics industry standard (SJ / T11223-2000) and the American ASTM B566-93 standard. The copper layer is made of refined copper with a purity of more than 99.97% through a "clad welding and drawing" process, and the finished rolled copper strip is concentrically coated on the outer surface of the aluminum rod wire, and is made through multiple passes of drawing and heat treatment Meet customer requirements for wire diameter and mechanical and electrical performance technical requirements. A solid metallurgical bond is formed between the copper layer and the aluminum rod core wire. The copper layer is evenly distributed in the circumferential direction and longitudinal direction, and has good concentricity. Make two equivalent metal materials into an inseparable whole, which can be drawn like a single metal. During the drawing process, copper and aluminum are reduced in proportion, and the volume ratio of the copper layer is relatively constant and its surface is bright, Round and without any defects.

In this way, the copper-clad aluminum wire has both good electrical conductivity, high strength, and strong solderability. Aluminum has many advantages such as low density, easy processing, etc. It also has the characteristics of uniform copper layer density, high compactness, and high stretchability. This kind of bimetal composite conductor not only has high signal transmission characteristics for the inner conductor of coaxial cable, it has become the most used conductor in cable television and other high-frequency applications. It is the material of choice for the inner conductor of coaxial cables and wires and cables in electrical equipment.

Copper clad aluminum wire characteristics:

1. DC resistivity: The DC resistivity of copper-clad aluminum wire is about 1.5 times that of pure copper wire. When the resistance is the same, the weight of copper-clad aluminum wire is about 1/2 of that of pure copper wire. According to the "skin effect" calculation, at high frequencies above 5MHZ, the resistivity is the same as that of pure copper wire. Therefore, its electrical performance is the same as that of pure copper wire for digital cables and high-frequency signal cables.

2. Compared with pure copper wire, copper-clad aluminum wire is not valuable to a thief, because it is almost impossible to separate the pure copper coating from the aluminum core wire. Therefore, it can receive an additional anti-theft effect.

3. The copper-clad aluminum wire is light in weight, which is convenient for transportation and installation, so it can also reduce labor costs.

4. It is more malleable than copper wire and does not generate insulating oxides like aluminum, so it is easier to process. And better conductivity.

5. The product is processed by the international leading "cover welding drawing method" production process. Even in the strict twisting test, it will not appear detachment, cracking or peeling like electroplated products. No harm.

Copper clad aluminum wire applications:

Copper-clad aluminum wire is widely used in the cable television industry. Copper-clad aluminum wire has become the standard material for coaxial cables in the United States. Because high-frequency signal transmission runs entirely on the outer layer of the conductor, copper-clad aluminum wires can replace copper wires of the same specification. In low frequency applications, the copper-clad aluminum has a loading capacity of 65% of the same size copper wire. Because of its light weight, it is softer than copper when large wire sizes are required. Copper-clad aluminum is used for battery cables and welding. Cables, building cables and electromagnetic conductors are also the best choice.

In addition, copper-clad aluminum wire can also be widely used in large capacity communication network signal transmission, control signal cable, light vehicle cable, welding cable emergency mobile cable, television excitation coil, deflection coil, ballast coil, etc. In terms of high-frequency signal transmission, it is used in:

1.50 ohm RF cable, flexible RF coaxial cable inner conductor material

2.Standard materials for inner conductor of cable television coaxial cable

3. Leaking cable

4.Data cable

5.Flexible coaxial RF cable

6.Inner conductor material of network cable

7. The inner conductor material of micro coaxial cable can be used in power transmission and low-frequency signal transmission: stranded wire material, power cable, conductor material for construction cloth wire, conductor material for automobile and locomotive special cable, conductor such as bus bar, computer cable, Control cables and other data cables

In terms of special electromagnetic wires, fuse materials can be used for audio, video conductor materials, power line conductor materials, computer peripheral wires, and computer cable conductor materials.

8. It can be used for coils or windings in electronic computers, mobile communication equipment, aerospace and military instruments.
