Aluminum coils are coiled products made from aluminum alloys through rolling. They offer advantages such as light weight, corrosion resistance, ease of processing, good thermal and electrical conductivity, and recyclability. Depending on the alloy grade (e.g., 1-series pure aluminum, 3-series aluminum-manganese alloys, 5-series aluminum-magnesium alloys) and surface treatment processes (oxidation, spraying, coating), their applications cover multiple fields including construction, packaging, electronics, and transportation.
