Description

technical field [0001] The invention relates to the technical field related to conductors, in particular to a tinned copper-clad ene alloy wire used for shielding layers of electric wires and cables and communication cables and a processing method thereof. Background technique [0002] Copper is widely used in the world as the most cost-effective conductor material. However, factors such as scarcity of resources and high prices have brought many difficulties to the production of material application companies. Research and development can replace pure copper with high performance, low price and abundant resources. Materials have become a top priority for material application companies, which can not only alleviate the problem of poor copper resources in my country, but also greatly reduce the production costs of related products.

AI Technical Summary

Problems solved by technology

[0003] In recent years, copper-clad aluminum alloy wire is widely used in my country to replace pure copper or aluminum-magnesium alloy as shielded braided wire. Its advantage is that the conductivity is similar to that of pure aluminum, but the strength can reach nearly 180 MPa ( 20°C soft state), which can meet the requirements of the braided wire for the shielding layer of communication cables, and also greatly reduce the production cost. At present, most of the braided wires and grounding wires for the shielding layer of communication cables in 3G and 4G mobile communication base stations use this material , but its weakness is: because the modified aluminum alloy rod is very sensitive to trace elements, it is more difficult to grasp during the smelting process, and the problem of unstable mechanical properties often occurs, resulting in frequent wire breakage and unstable production efficiency. Due to the limitations of strength and electrical conductivity, it is still unable to replace pure copper in some applications that require high electrical and mechanical properties of wire materials (such as new energy vehicles, etc.)
