Comparing Different Types of Extruded Aluminum Pipes

Extruded aluminum pipes offer a versatile solution for a wide range of industrial and architectural applications. They are lightweight, strong, and resistant to corrosion, making them ideal for use in various environments. Here is a comprehensive comparison of different types of extruded aluminum pipes to help you make an informed decision:

Alloy Composition

The alloy composition of an extruded aluminum pipe determines its overall properties. Common alloys include:

6061: This general-purpose alloy offers a good balance of strength, corrosion resistance, and workability.

6063: Similar to 6061, this alloy provides increased corrosion resistance and is suitable for marine and outdoor applications.

6082: With higher strength than 6061, this alloy is ideal for structural components and high-stress environments.

7075: Known for its exceptional strength-to-weight ratio, this alloy is used in aerospace and automotive industries.


Temper refers to the thermal treatment process that modifies the properties of the aluminum alloy. Common tempers include:

O (Annealed): Soft and ductile, this temper is suitable for bending and forming applications.

H12 (Strain Hardened): Slightly hardened, this temper provides increased strength and resistance to bending.

T4 (Solution Heat Treated): Strong and somewhat ductile, this temper is ideal for structural components and products that require moderate strength.

T6 (Artificially Aged): Hard and wear-resistant, this temper is used in applications that demand high strength and durability.


Extruded aluminum pipes are available in various shapes, including:

Round: The most common shape, offering excellent structural strength and fluid flow characteristics.

Square: Suitable for applications that require a flat surface or high torsional strength.

Rectangular: Provides a combination of structural strength and space optimization.

Oval: Offers a compromise between round and rectangular shapes, with improved aerodynamics and space utilization.

Size and Thickness

The size and thickness of extruded aluminum pipes determine their load-bearing capacity and suitability for specific applications. Sizes range from small diameters of a few millimeters to large diameters exceeding 200 millimeters. Wall thickness can vary from a few tenths of a millimeter to several millimeters.

Surface Finish

The surface finish of extruded aluminum pipes can enhance their appearance and performance:

Mill Finish: The raw, untreated surface retains the natural grain of the aluminum alloy.

Anodized Finish: An electrochemical process that creates a protective oxide layer, improving corrosion resistance and appearance.

Powder Coated Finish: A durable coating applied electrostatically, providing a wide range of colors and textures.

Brushed Finish: A mechanical process that creates a subtle, linear texture on the surface.


The type of extruded aluminum pipe you choose depends on the specific requirements of your application. By considering factors such as alloy composition, temper, shape, size, thickness, and surface finish, you can select the optimal pipe for your project. Extruded aluminum pipes offer a combination of lightweight, strength, corrosion resistance, and versatility, making them a valuable choice for various industries and applications.
