1. Understanding Aluminum Extrusion

Aluminum extrusion is a process used to create objects with a fixed cross-sectional profile. This is achieved by pushing aluminum through a die of the desired shape. The result is a long piece of aluminum with the same profile as the die opening. This method allows for the creation of complex and precise shapes.

Here’s the interesting part, aluminum extrusions are known for their strength and versatility. They are used in various industries, from construction to automotive, due to their lightweight yet durable nature. The flexibility of the extrusion process also allows for a wide range of applications, making it a popular choice for custom solutions.

2. How Aluminum Extrusion is Made

The aluminum extrusion process starts with a solid aluminum billet, which is a cylindrical piece of aluminum. This billet is heated to around 900°F to 925°F to make it soft enough for extrusion. Once heated, the billet is transferred to a loader, where it is pushed into a container. A hydraulic press then forces the aluminum through a steel die, shaping it into the desired profile.

As the aluminum is pushed through the die, it takes on the shape of the die’s opening, creating a long piece with a consistent cross-section. The extruded aluminum is then cooled by air or water, to harden it. Once cooled, the aluminum is stretched to straighten bends that occur during extrusion. And the best part is, the extruded aluminum is cut to the required length and undergoes further treatments, such as aging.


3. Advantages of Aluminum Extrusion Over Other Metals

Aluminum extrusion offers numerous benefits compared to other metals, making it a popular choice in various industries. Its unique properties allow for versatile and efficient manufacturing processes. Here are the main advantages:
