Hot/Cold Rolled Aluminum Coil Description
Aluminum coil is a rolled product made from high-purity aluminum or aluminum alloys through processes such as casting, hot rolling, and cold rolling. It is supplied in continuous coil form, making it easy for transportation, storage, and further processing.
Common alloys include 1xxx series (pure aluminum such as 1050, 1060, 1100), 3xxx series (anti-rust aluminum such as 3003, 3105), 5xxx series (high corrosion resistance such as 5052, 5754), and 8xxx series (packaging materials such as 8011). Each alloy has unique properties suitable for specific applications.
Hot Rolled Aluminum Coil is produced by heating aluminum ingots above the recrystallization temperature and rolling them through a hot rolling mill in multiple passes. High-temperature processing ensures fine grain structure and stable performance, making hot-rolled aluminum coil suitable for further processing.
Cold Rolled Aluminum Coil is produced by annealing hot rolled aluminum coil and then rolling it at room temperature in multiple passes, reducing thickness and improving surface finish.
Hot Rolled Aluminum Coil and Cold Rolled Aluminum Coil are two major types of aluminum coil products widely used in construction, transportation, packaging, electronics, and decorative industries. Although both are made from high-quality aluminum alloys, their production processes, surface characteristics, and applications are different.
By understanding the differences between Hot Rolled Aluminum Coil and Cold Rolled Aluminum Coil, customers can choose the right material that best fits their project requirements.
