Thin aluminum sheet refer to thin aluminum alloy sheets, usually between 0.2 mm and 6 mm thick. They are widely used in many fields due to their light weight, corrosion resistance, and easy processing.

The production process of thin aluminum sheet mainly includes steps such as smelting, casting, rolling, and surface treatment. First, the aluminum ingot is heated to 300°C to 500°C, hot rolled, and gradually thinned to the required thickness. Then, it is cold rolled and further thinned at room temperature to improve the surface finish and strength. Some aluminum alloys may be heat treated to improve their mechanical properties. After rolling, the aluminum sheet needs to be cleaned and surface treated, such as anodizing or spraying, to improve corrosion resistance and aesthetics. Finally, the aluminum sheet is cut into the required size and packaged for transportation and storage. Throughout the process, strict quality inspections ensure that the product meets standard requirements.

Features of thin aluminum sheet:
- Light weight:
Compared with other metal sheets, thin aluminum sheets are significantly lighter in weight. For example, when used in electronic products, they can effectively reduce the overall weight of the product and facilitate carrying and use.
- Good thermal conductivity:
It can quickly conduct heat and is often used in equipment that needs to dissipate heat, such as computer CPU heat sinks.
- Corrosion resistance:
Aluminum itself has a certain degree of corrosion resistance. Thin aluminum sheets are not easy to rust and corrode in general environments. Some aluminum billboards outdoors can maintain their appearance and performance for a long time.
- Easy to process and form:
It can be made into products of various shapes through various processing methods such as stamping, bending, and stretching to meet the needs of different application scenarios, such as the shell of lamps and aluminum foil for packaging.
- Beautiful surface:
It has good gloss and texture. After surface treatment, different appearance effects can be obtained. It is often used in the field of decoration.

Application range of thin aluminum sheet:
- Electronic products:
Such as the shell of mobile phones and tablets, as well as radiators and shielding covers in electronic devices, etc., taking advantage of their light weight, good thermal conductivity and easy processing.
- Home appliances:
The shells and liner of home appliances such as refrigerators and air conditioners, as well as the liner of microwave ovens, are both beautiful and corrosion-resistant, and can also reduce the weight of home appliances.
- Packaging:
Used for packaging of food, medicine, cosmetics, etc., such as aluminum foil packaging, which can effectively block light, moisture and air, and extend the shelf life of products.
- Building decoration:
Can be used for indoor ceiling decoration, wall decoration lines, and outdoor curtain wall decoration, etc., to enhance the beauty of the building.
- Advertising signs:
Make billboards, signboards, etc., easy to process into various shapes and patterns, and can be used outdoors for a long time.
