what is 3003 aluminum pipe use for?

3003 Aluminum Pipe

3003 aluminum pipes are widely used in applications that require good formability, high plasticity, and excellent welding properties. They are commonly found in low-load components operating in liquid or gaseous environments, such as fuel lines, lubrication systems, and small containers. These pipes are also suitable for deep-drawn parts and rivet wiring due to their favorable workability.

Temper: O, H112, H14, H24

Properties
3003 is an Al-Mn alloy, known as one of the most commonly used rust-proof aluminum alloys. It has moderate strength, slightly higher than that of industrial pure aluminum, but it cannot be strengthened through heat treatment. Instead, its mechanical properties are improved by cold working. In the annealed condition, it exhibits high plasticity, while in semi-cold worked conditions, it still maintains good formability. However, when fully cold worked, its plasticity decreases. The alloy offers excellent corrosion resistance and weldability, though its machinability is relatively poor.

Applications
3003 aluminum pipes are ideal for applications requiring good formability, corrosion resistance, and weldability. They are often used in storage tanks, pressure vessels, pipelines, heat exchangers, cosmetic containers, photocopier drums, and shipbuilding materials. Compared to 1xxx series alloys, 3003 provides better strength while maintaining good workability and corrosion resistance, making it a preferred choice in many industrial settings.
