What is aluminium alloy extrusion?

Aluminium alloy extrusion refers to the process of elongating or stretching an aluminium alloy material, typically through mechanical or thermal means. This extrusion can result in changes to the material’s dimensions, shape, or properties. It’s often used in manufacturing to make products with certain qualities, like making them stronger, more flexible, or with custom shapes. The extrusion process can involve techniques like extrusion, rolling, casting or forging, depending on the desired outcome and the properties required for the final product.

Aluminium Alloy Extrusion Process step by step

The aluminum alloy extrusion process is a method of shaping aluminum into specific profiles or cross-sectional shapes. It’s widely used in various industries, including construction, automotive, and manufacturing. Here’s a step-by-step overview of the aluminum alloy extrusion process:

1.Billet Preparation:

The process begins with the preparation of a solid cylindrical billet, typically made of aluminum alloy. The billet is preheated to a specific temperature to make it more malleable for extrusion.

2.Die Design and Setup:

The die is a tool used to shape the aluminum. It’s often custom-designed to create the desired profile. The die is mounted at the end of the extrusion press.

3.Extrusion Press:

The heated billet is loaded into the extrusion press. The press is a powerful machine with a hydraulic or mechanical system that exerts tremendous force.

4.Extrusion Process:

The press pushes the heated billet through the die. The combination of pressure and heat causes the aluminum to flow through the die’s opening, taking on the desired shape as it exits on the other side. This is where the extrusion occurs.


After extrusion, the aluminum profile is rapidly cooled using air or water. This cooling process helps to set the shape and maintain the profile’s structural integrity.

6.Stretching and Cutting:

The extruded profile may undergo stretching to align the molecules and improve mechanical properties. It’s then cut into specific lengths.

7.Aging (Optional):

Depending on the type of alloy and the properties you want, the extruded profiles might go through a heat treatment process known as aging. This process can make them even stronger.

8.Quality Control:

The extruded aluminum profiles are inspected for defects and conformity to the design specifications. This can include dimensional checks, surface quality assessment, and other quality control measures.

9.Finishing (Optional):

Depending on how they’ll be used, the extruded profiles might go through different finishing processes like anodizing, painting, or powder coating. This is done to make them look better and protect them from corrosion.

10.Packaging and Shipping:

The completed extruded profiles are packed and readied for shipping to customers or for use in more manufacturing steps.
