Aluminum Sheet Thickness
Aluminum Plate Thickness Selection Guide
- Application requirements: According to the specific application requirements and use environment, select the appropriate aluminum plate thickness to ensure that the aluminum sheet can meet the required strength and load-bearing capacity.
- Cost considerations: Thicker aluminum sheets usually mean higher costs, so there is a trade-off between performance and cost.
- Processing performance: Thicker aluminum plates may increase difficulty and cost during processing and forming, and processing performance and forming technology need to be considered.
The thickness of the aluminum sheet refers to the actual thickness of the aluminum plate, which directly affects the strength, stiffness and load-bearing capacity of the aluminum sheet. Aluminum plates of different thicknesses are suitable for different application fields, such as architectural decoration, aerospace, automobile manufacturing, etc.
Aluminum Sheet Thickness in Inches (in)
Aluminum Sheet Thickness in Gauge (ga)
“Gauge”, abbreviated as “Ga”, is a length measurement unit of diameter originating in North America and belongs to the Browne & Sharpe measurement system. Originally used in the fields of medicine and jewelry, the larger the number, the smaller the diameter. Later, it was promoted for thickness. When non-ferrous metal plates and steel plates have the same value ga, their thicknesses are actually different; plates and pipes with the same value ga also have different values. The specific values are detailed in the thickness table:

Common Aluminum Sheet Thicknesses and Applications
Thickness (mm) | Common Uses |
1mm | Lightweight cladding or paneling, especially when used in the construction of aluminum composites or sandwich panels. |
3mm | Typically found on slightly thicker panels such as interior wall coverings or perforated privacy screens. |
5mm | The 5 mm aluminum sheet is at the upper end and is often still called a sheet rather than a plate due to its thickness. |
6mm | It is often chosen as a sidewalk and floor covering for high traffic areas, especially when sold as checkered plate. |
10mm | Thicknesses of 10 mm and above are typically manufactured to 6082 alloy specifications, making them suitable for sturdier applications. |
