1100 Aluminum Alloy Sheet

Detailed Chemical Composition Parameters

The 1100 aluminum sheet maintains strict and standardized chemical component control during production. The aluminum element content is controlled above 99.0%, with the main impurity elements strictly limited within industrial standards. The silicon content is controlled below 0.95%, iron content no more than 1.00%, copper content ranges from 0.05% to 0.20%, and manganese, zinc, magnesium and other trace impurities are kept in extremely low proportions. This precise component control ensures that 1100 aluminum sheet will not have material quality differences and performance fluctuations in batch production, realizing consistent product quality for long-term bulk procurement.

Core Physical and Mechanical Properties

In terms of physical properties, 1100 aluminum alloy sheet has a density of 2.71g/cm³, a melting point of 660℃, and excellent thermal conductivity and electrical conductivity. Its thermal conductivity can reach 222 W/(m·K), which enables it to perform well in heat dissipation and heat conduction scenarios. The linear expansion coefficient is stable, ensuring no obvious deformation under normal temperature changes. For mechanical properties, the tensile strength of annealed state O temper 1100 aluminum sheet is between 75MPa to 150MPa, the yield strength is about 30MPa to 130MPa, and the elongation rate can reach 10% to 35%. Different tempers including H14, H18 can be customized, among which H14 temper has moderate hardness and good balance of toughness and strength, while H18 temper features high hardness and strong compression resistance, meeting different processing and usage requirements.
 

Superior Product Characteristics

1100 aluminum alloy sheet has outstanding natural corrosion resistance. Thanks to its high-purity aluminum composition, a dense and stable oxide film will be automatically formed on the surface when exposed to air, which can effectively isolate air, moisture and weak corrosive substances, avoiding oxidation and rust. It can maintain stable performance in conventional atmospheric, humid and mild industrial environments without anti-corrosion coating treatment, greatly reducing subsequent processing costs.

This aluminum sheet boasts excellent processing and forming performance. It has extremely high ductility and plasticity, supporting various deep processing technologies such as bending, stamping, stretching, cutting, welding and rolling. No cracking, deformation or brittle damage will occur during cold and hot processing, and it can be made into various complex-shaped parts and finished products. In addition, the surface of 1100 aluminum sheet is smooth, flat and uniform, with no roller marks, scratches or oxidation spots. It has good anodizing, spraying and polishing performance, and can perfectly adapt to surface decoration treatment requirements.

Another prominent advantage of 1100 aluminum sheet is its lightweight feature and stable physical stability. Compared with steel materials, it has a lighter weight, which can effectively reduce the overall weight of equipment and components. Meanwhile, it has non-magnetic, shock-resistant and low-temperature resistant properties, and will not change its mechanical performance in low-temperature environments, with wide environmental adaptability.
