Thin Aluminium Sheet Suppliers

Haomei is one of the leading thin aluminium sheet suppliers based in China with over 20 year experience! There are different classification methods for aluminum sheet. The common classification method is to classify according to thickness, which can be roughly divided into thin aluminum sheet 0.15-2.0mm, conventional aluminum sheet (2.0-6.0mm), medium aluminum plates (6.0-25.0mm), and thick aluminum plates (25-2.0 mm). 200mm), ultra-thick aluminum plate (above 200mm). The production process of thin aluminium sheet is processing aluminum and aluminum alloys into rectangular single sheets or coils through smelting, ingot casting, various pre-rolling preparations, flat roll rolling, heat treatment, and finishing processes.
 

Compared with hot rolling, the main feature of cold rolling is that thinner aluminum sheet can be obtained. The thickness of the hot-rolled slab is usually 6-8mm. The minimum thickness is 2.5mm-3.0mm. Due to the large temperature drop of the rolled piece during the hot rolling process, it is difficult for the hot rolling to continue rolling to a thinner thickness, while the cold rolling easily causes the rolled piece to continue to become thinner. Generally, cold rolling mills can roll to 0.5-4.5mm, and more advanced cold rolling mills can roll out ultra-thin aluminium sheet with a thickness of 0.1mm-0.2mm. Compared with hot rolling, the main characteristics of cold rolling are that cold rolling can produce products with precise dimensions, uniform thickness, good flatness and surface gloss, good product structure and high surface quality.
 

The thin aluminium sheet suppliers have cold rolled and hot rolled production line to product aluminum sheet plate. Because cold rolling mills have higher precision than hot rolling mills, the comprehensive automatic control level of cold rolling mills is higher. For example, more advanced cold rolling mills are equipped with automatic control devices for thickness and shape. In addition, cold rolling can roll high-quality aluminum sheets by using rolls with higher finish.
