3003 aluminum has the same properties as 1100 but is stronger. This soft aluminum pipe is essentially commercially pure aluminum pipe with manganese added to increase its strength. It has excellent corrosion resistance and processing performance, and can be deep drawn or spun, welded or brazed. Length received was 50 feet.

3003 aluminum pipe is mainly composed of aluminum, copper and manganese. Aluminum is the main element, accounting for 97-98% of the total composition. The remaining 2-3% consists of copper and manganese, these elements are added to make this grade of aluminum alloy stronger and easier to weld than other grades of aluminum; it has been widely used in engineering applications due to its strength and heat-treatability for decades. In addition to its ductility and long-term corrosion resistance, its relatively low cost compared to other alloys makes it a wise choice for many industrial projects.
