3M03 Aluminum Sheet Supplier: Zggdmetal; Standard: ASTM B209; Thickness: 1.0mm~250mm; Bulk purchases supported.
The 3M03 aluminum sheet & plate is part of the Aluminum–Manganese (Al–Mn) alloy series and is commonly identified internationally as the 3003 aluminum alloy. It is widely used in both industrial manufacturing and architectural applications due to its excellent resistance to corrosion, dependable formability, and balanced mechanical strength. These properties allow the material to perform well in a wide range of fabrication processes.
Unlike heat-treatable aluminum alloys, the strength of 3M03 aluminum sheet & plate is developed through cold working rather than heat treatment. This manufacturing characteristic helps the material maintain stable mechanical performance while remaining easy to cut, bend, weld, and shape during processing.
Thanks to its durability, recyclability, and consistent performance, 3M03 aluminum sheet & plate is frequently used in architectural decoration, aluminum curtain wall panels, roofing systems, and various industrial components.
The addition of manganese improves the alloy’s ability to resist atmospheric corrosion. This makes 3M03 aluminum particularly suitable for outdoor structures and humid environments.
3M03 aluminum can be easily bent, stamped, or rolled into different shapes. Its high ductility allows manufacturers to create complex components without cracking.
With a lower density than steel and higher strength than pure aluminum alloys such as 1100, 3M03 aluminum offers a balanced combination of weight reduction and structural stability.
This alloy can be welded using common welding methods. The weld area maintains good mechanical performance and fatigue resistance.
3M03 aluminum sheet responds well to anodizing, coating, painting, and other finishing processes, ensuring long-lasting decorative and protective surfaces.
Aluminum materials are fully recyclable, making 3M03 aluminum sheet & plate a sustainable choice for modern construction and manufacturing.
