1050 Aluminum Alloy Sheet

Chemical Composition & Purity Standards

The core advantage of 1050 aluminum alloy sheet lies in its high material purity. The standard aluminum content reaches 99.5% minimum, which is significantly higher than that of ordinary 1100 aluminum. Strict industrial standards are implemented for all impurity elements to ensure stable and consistent material performance. The iron content is controlled below 0.40%, silicon content less than 0.25%, while copper, manganese, magnesium, zinc and other trace impurities are strictly limited to ultra-low ranges. The low impurity formula effectively avoids performance fluctuations such as reduced conductivity, poor welding stability and rough surface texture caused by excessive miscellaneous elements, making 1050 aluminum sheet more suitable for high-standard industrial supporting applications.
 

Physical & Mechanical Performance Parameters

1050 aluminum alloy sheet possesses outstanding physical properties suitable for professional industrial use. Its standard density is 2.70 g/cm³, with a melting point of 660.3℃, presenting excellent high-temperature resistance and structural stability under normal working conditions. The material has extremely high thermal conductivity up to 230 W/(m·K) and stable electrical conductivity, which is one of its core advantages over other ordinary aluminum sheets. This superior conduction performance ensures efficient heat dissipation and stable current transmission in electrical and thermal equipment.

In terms of mechanical properties, 1050 aluminum sheet supports multiple tempers to adapt to different processing requirements. The O temper material delivers ultra-high plasticity with an elongation rate of 33% or above, suitable for deep drawing, stretching and complex bending processes. Conventional H14 temper provides balanced hardness and toughness, with tensile strength stably maintained between 110MPa to 130MPa and yield strength around 95MPa. H18 high-hardness temper offers tensile strength up to 150MPa, which can meet the requirements of stamping, shaping and structural assembly that need certain rigidity. The overall mechanical performance is uniform, with no brittle fracture or strength attenuation in batch processing.
 

Core Product Characteristics & Performance Advantages

1050 aluminum alloy sheet has ultra-reliable natural corrosion resistance. Thanks to its high-purity aluminum matrix and extremely low impurity ratio, the material can form a dense and uniform protective oxide film on the surface in atmospheric and humid environments. Compared with ordinary aluminum materials, it has stronger resistance to atmospheric oxidation, mild acid and alkali corrosion, and can maintain a smooth surface and stable structural performance for a long time without additional anti-corrosion coating treatment, greatly reducing later maintenance costs for industrial equipment.

This grade of aluminum sheet features excellent superplastic forming performance. Its internal grain structure is fine and uniform, with no internal impurities or pores. It can adapt to various cold working processes including precision cutting, CNC bending, deep drawing, rolling and argon arc welding. During high-precision processing, the material will not produce cracking, edge warping, surface wrinkling or rebound deformation, which fully meets the production requirements of precision industrial parts and thin-wall components. In addition, the surface of 1050 aluminum sheet is smooth, flat and delicate, with good anodizing, oxidation coloring, spraying and polishing adaptability, delivering high finished product appearance quality.

Another unique feature of 1050 aluminum sheet is its non-magnetic property and stable low-temperature performance. The material will not generate magnetic interference during equipment operation, and its mechanical toughness and structural strength will not deteriorate in low-temperature environments. It can work stably in extreme temperature and complex working conditions, with strong environmental adaptability and long service life.
