what is 3003 aluminum pipe use for?

3003 aluminum pipes are widely used in applications that require good formability, high plasticity, and excellent welding properties. They are typically used for low-load components operating in liquid or gas environments, such as fuel lines, lubrication pipelines, and small containers for liquids. These pipes are also suitable for deep-drawn parts, rivet wiring, and other similar applications where flexibility and ease of fabrication are important.

Temper: O, H112, H14, H24

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

Applications
Due to its good formability, weldability, and corrosion resistance, 3003 aluminum pipes are ideal for applications requiring both strength and durability. They are commonly 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.
