Copper-clad aluminum annealed wire is a type of conductive material made by combining copper and aluminum, integrating the advantages of both materials. In this composite, aluminum serves as the core, with a thin layer of copper wrapped around it. Through this structure, it combines the excellent electrical conductivity of copper with the lightweight characteristics of aluminum. “Annealing” refers to a heat treatment process that this material undergoes during production, which is known as annealing.

1. Good conductivity: The copper layer of copper coated aluminum wire, provides good conductivity, making the copper clad aluminum annealing wire suitable for applications that require good electrical conductivity.
2 Lightweight: The aluminum core makes the overall material lighter than pure copper, helping to reduce the weight of the final product.
3. cost-effectiveness: Copper clad aluminum annealing wire is more economical than all copper wire because aluminum is cheaper than copper and the copper layer is thinner.
4. Good flexibility and plasticity: The annealing process improves the flexibility and plasticity of the material, making it easier to process and form.
5. Wide applicability: Due to its comprehensive performance, copper clad aluminum annealing wire can be used in various applications, including power transmission lines, cables, transformers, motor windings, etc
