Aluminum coil is a lightweight, corrosion-resistant product with excellent electrical and thermal conductivity. Produced through processes such as casting, rolling, and calendering, it is widely used in architecture (exterior walls and curtain walls), electronic product housings, packaging, automotive manufacturing, aerospace, and other fields.

Aluminum coil is categorized into various series based on alloying elements (such as 1-series pure aluminum, 3-series aluminum, 5-series aluminum, 6-series aluminum, and 7-series aluminum) to meet diverse engineering needs.
