The difference between hot rolled and cold rolled aluminium

Alloy aluminum coil can be divided into cold rolled and hot rolled aluminium coil roll, the main difference is the difference between anodic oxidation, hot rolled aluminum coil can do anodic oxidation.

The aluminum coil manufacturer to place the space to strengthen the management of air-dry to ensure no water in the compressed air. Strengthen the management of rolling oil, the water content controlled below 0.04%. Aluminum coil/foil roll packaging should be sealed while each volume should be placed in the amount of desiccant.

Aluminum processing is also known as plastic forming, according to the deformation of aluminum in the process of deformation andstress (stress - strain state) is divided into: casting, forging, extrusion, spinning, drawing, rolling, forming Cold pressure, deep red) and other processing methods.
Cold rolled aluminum coil and hot rolled aluminum coil in use is different. Cold rolled aluminum coils are used for molds, hot rolled aluminum coil suitable for drawing tension.The same material due to different production processes, its great difference in physical properties.
