Introduction to the production process of copper-clad aluminium wire

The main production processes for copper-clad aluminium wire are:
1. Drawing process: The production process for copper-clad aluminium wire is relatively complex. The aluminium wire needs to be surface treated first, and then the copper wire is wound around the aluminium wire through a wire drawing machine to form copper-clad aluminium wire.
2. Annealing process: The copper-clad aluminium wire needs to be annealed during the production process to relieve the internal stress generated during the wire drawing process and improve its electrical conductivity.
3. Surface treatment: The copper-clad aluminium wire needs to be surface treated during the production process to improve its corrosion resistance and electrical conductivity. Common surface treatment methods include tinning and silver plating.
