Aluminum Extrusions: Benefits, Designing, Types, Uses and Manufacturing Processes


Aluminum extrusions are a popular choice for many applications due to their lightweight, durable, and cost-effective properties. They are also easy to customize and can be used in a variety of industries, from automotive and aerospace to architectural and industrial. This article will provide an overview of aluminum extrusions, explain the benefits of using them, discuss design considerations when using them, outline the different types available, explore creative uses for them, and provide a comprehensive guide to the manufacturing process.

Overview of Aluminum Extrusions

Aluminum extrusions are metal components that are formed by forcing heated aluminum alloy through a die that has been shaped according to the desired profile. This process creates long, continuous pieces with uniform cross sections, which can then be cut to the length needed for a particular application. The aluminum alloy used in extrusions is usually 6061 or 6063, both of which are strong and lightweight alloys that are corrosion-resistant and ideal for a variety of applications.

Benefits of Aluminum Extrusions

The use of aluminum extrusions offers numerous advantages, including their lightweight properties, durability, corrosion resistance, and cost effectiveness. Aluminum extrusions are also highly customizable, allowing for precise shapes and sizes to be created. Additionally, aluminum extrusions are easy to work with and can be machined, drilled, tapped, and welded with relative ease. Finally, they can be anodized or painted to achieve the desired look or finish.

Designing with Aluminum Extrusions

When designing with aluminum extrusions, there are several factors to consider. First, it is important to determine the size and shape of the extrusion needed for the application. This will help ensure that the chosen extrusion will meet the requirements of the project. Additionally, it is important to consider the wall thickness of the extrusion, as this will affect the strength and durability of the final product. Finally, it is important to consider any additional features such as holes, slots, or notches that may be necessary for the design.

Types of Aluminum Extrusions

There are several different types of aluminum extrusions available, each with its own set of advantages and disadvantages. The two most common types are solid and hollow extrusions. Solid extrusions are typically stronger and more durable than hollow extrusions, but they are also heavier and more expensive. Hollow extrusions are lighter and less expensive, but they are not as strong and durable as solid extrusions. Other types of extrusions include seamless, flat, and tubular extrusions.

Creative Uses for Aluminum Extrusions

Aluminum extrusions can be used in a variety of creative ways, from furniture and lighting fixtures to frames and art installations. They are also popular for use in industrial applications, such as machine guards and conveyor systems. When considering these unique applications, it is important to ensure that the extrusion chosen meets the requirements of the project and that the design and manufacturing processes are properly followed.

Aluminum Extrusion Manufacturing Processes

The aluminum extrusion manufacturing process involves several steps, beginning with the selection of the appropriate alloy and ending with the delivery of the finished product. The first step is to create a billet, which is a block of aluminum alloy that has been heated and then pressed into the desired shape. The billet is then placed in a container known as an extrusion press, where it is subjected to high pressure and heat. This causes the billet to become malleable and flow through the die, creating the desired profile. After the extrusion is removed from the press, the excess material is trimmed away, and the extrusion is subjected to various finishing processes such as heat treating, painting, and anodizing.


Aluminum extrusions offer numerous benefits, including their lightweight and durable properties, corrosion resistance, and cost effectiveness. They are also highly customizable, making them ideal for a variety of applications. Additionally, they come in several different types, each with its own set of advantages and disadvantages. Finally, they can be used in creative ways, and the manufacturing process is relatively straightforward.

Aluminum extrusions are an excellent choice for many applications, and understanding their benefits, design considerations, types, uses, and manufacturing processes can help ensure that you get the most out of your aluminum extrusions.
