Product Details

3003 Aluminum Rod for Sale

3003 aluminum is a widely used aluminum-manganese (AL-Mn) alloy known for its excellent anti-rust properties. While its strength is not high compared to other alloys, it can be improved through cold processing methods. In the annealed state, 3003 aluminum is highly malleable and exhibits high plasticity, making it easy to form and shape. When subjected to semi-cold hardening, it maintains good plasticity while gaining some additional strength. However, further cold hardening reduces plasticity while increasing strength. 3003 aluminum bar offers good corrosion resistance, making it suitable for applications where protection against corrosion is essential. It also has good weldability but tends to have poor machinability.

The main purpose of 3003 aluminum bars is their wide range of applications where a combination of corrosion resistance, formability, and moderate strength is required. These rods find extensive use in construction for roof panels, siding, and architectural trim, thanks to their corrosion resistance, ensuring long-lasting performance in outdoor environments. In the HVAC industry, 3003 aluminum bars are utilized in heat exchangers due to their excellent thermal conductivity and resistance to corrosion. The food and beverage industry benefits from the alloy’s non-toxic properties and corrosion resistance, using it in food processing equipment, storage tanks, and beverage cans. Additionally, 3003 aluminum rods are employed in chemical equipment, refrigeration components, and general fabrication tasks, where their corrosion resistance, thermal conductivity, and formability contribute to their effectiveness. Whether in electrical conductors, chemical applications, or diverse fabrication projects, 3003 aluminum bar serve crucial roles in various industries.
