what is 3003 aluminum pipe use for?

3003 aluminum pipes are commonly used in applications that require good formability, high plasticity, and excellent welding properties. They are ideal for low-load components operating in liquid or gaseous 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.

Temper: O, H112, H14, H24

Properties
3003 is an Al-Mn alloy, one of the most widely 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 through cold working. In the annealed state, 3003 exhibits high ductility. When semi-cold worked, it still maintains good formability, while cold working reduces its ductility. It offers excellent corrosion resistance and good weldability, though its machinability is relatively poor.

Applications
3003 aluminum pipes have excellent formability, corrosion resistance, and weldability. They are ideal for applications requiring good forming performance and high corrosion resistance, especially where both properties are needed. Compared to 1xxx series alloys, 3003 provides better strength. Common uses include storage tanks, pressure vessels, pipelines, heat sinks, cosmetic containers, photocopier drums, and shipbuilding materials.

Chemical Composition

The chemical composition of 3003 aluminum is primarily composed of aluminum with small amounts of manganese and other elements. Here is a detailed breakdown:

Mechanical Properties

3003 aluminum pipes offer a balanced set of mechanical properties, making them suitable for a wide range of applications. Below is a reference table of key mechanical properties:

These properties make 3003 aluminum an excellent choice for a variety of industrial and commercial applications where durability, formability, and corrosion resistance are essential. Whether in transportation, construction, or manufacturing, 3003 aluminum pipes provide reliable performance and long-term value.
