3003 aluminum rod bar is an aluminum alloy with manganese as the primary alloying element, also known as "rust-proof aluminum." It features excellent formability, corrosion resistance, and workability. Compared to the 1000 series aluminum, 3003 aluminum alloy has about 20% higher strength, and its strength can be further increased through cold working.
Due to its good corrosion resistance, the 3003 aluminum rod is commonly used in outdoor projects and equipment that comes into contact with chemicals, such as storage tanks, pipelines, chemical equipment, kitchenware, and decorative parts. Additionally, it has high thermal and electrical conductivity, making it suitable for applications requiring efficient heat dissipation.

1100 aluminum rod vs. 3003 aluminum rod
Both 1100 aluminum rods and 3003 aluminum rods are non-heat-treatable alloys with relatively low strength. The main differences are:
- Alloy Composition: 1100 aluminum contains 99% aluminum, offering excellent corrosion resistance and workability, but it has lower strength. 3003 aluminum, on the other hand, contains a small amount of manganese (around 1.2%), making it stronger than 1100 aluminum and significantly enhancing its corrosion resistance.
- Strength: 1100 aluminum has lower strength, making it suitable for applications requiring extreme ductility and formability. 3003 aluminum is approximately 20% stronger than 1100 aluminum, making it suitable for applications requiring moderate strength and easy formability.
- Formability and Weldability: 1100 aluminum has excellent formability, making it easy to weld and process. While 3003 aluminum is slightly less formable, it offers good weldability and workability, making it ideal for processing complex shapes.
