Cold rolled aluminum coil usually refers to the cold rolled aluminum coil processed by the
cold rolling process of the cast rolled material, which is usually called the cast rolled
aluminum coil. Cold rolling is a common metal processing process. It is to reduce the
thickness of the material and improve its surface quality and mechanical properties by
further processing at room temperature or slightly below room temperature after the metal
is heated (usually hot rolled). As for the aluminum coil casting process, it may be relatively
simple. Aluminum ingot---aluminum liquid---static furnace---cast rolled coil, which is a
conventional processing process for raw materials.

Cold-rolled aluminum coils are more inclined to non-heat treatment processes. For
example, our common 1060 aluminum coils, 3003 aluminum plates, 3105 aluminum coils,
5052 aluminum plates, 1100 aluminum plates, etc. are all cold-rolled aluminum coils, which
are suitable for simple stamping, but not suitable for large-scale finished product
stamping. Therefore, the main application areas are currently mainly concentrated in
building exterior walls, signs and signs, etc.

Features of cold-rolled aluminum coil:
1. High surface finish: The cold rolling process can improve the surface quality of the
aluminum coil, making it smooth and shiny.
2. High thickness accuracy: The thickness of the cold-rolled aluminum coil can be very
precise, suitable for applications with strict thickness requirements.
3. Excellent mechanical properties: The cold rolling process can improve the strength and
hardness of aluminum, especially in applications where high strength is required.
4. Good processability: Due to its good strength and ductility, cold-rolled aluminum coils
are easy to process later, such as shearing, stamping, stretching, etc.
