Properties and Benefits

Square aluminum extrusions are characterized by their exceptional properties that make them ideal for various applications. These properties include:

– High Strength-to-Weight Ratio: Aluminum extrusions are strong and lightweight, making them a preferred material for industries where weight reduction is crucial, such as aerospace and transportation.

– Excellent Corrosion Resistance: Aluminum is highly resistant to corrosion, making square aluminum extrusions suitable for outdoor applications and in environments prone to moisture.

– Electrical Conductivity: Aluminum is a good conductor of electricity, which makes square aluminum extrusions ideal for electrical applications.


The versatility of square aluminum extrusions makes them suitable for a wide range of applications. Some common industries that utilize square aluminum extrusions include:

– Construction: Square aluminum extrusions are used in various architectural applications, such as window frames, door frames, curtain walls, and roofing systems.

– Automotive: Square aluminum extrusions are used in vehicle frames, body panels, and interior components due to their lightweight and strength.

– Aerospace: Square aluminum extrusions are used in aircraft components, including wings, fuselage frames, and landing gear, due to their high strength and light weight.

Manufacturing Process

The manufacturing process of square aluminum extrusions involves several steps:

– Billet Preparation: An aluminum billet is heated to a semi-solid state and placed in a press.

– Extrusion: The billet is forced through a die, which shapes the molten aluminum into the desired square cross-section.

– Cooling: The extruded profile is cooled rapidly to achieve the desired metallurgical properties.

– Finishing: The extrusion may undergo additional processes such as straightening, cutting, and surface treatments to meet specific requirements.

Design Considerations

When designing with square aluminum extrusions, several factors should be considered:

– Size and Shape: The dimensions and shape of the square extrusion should be carefully selected to meet functional and aesthetic requirements.

– Tolerances: Specify appropriate tolerances to ensure precision and accuracy in the finished product.

– Mechanical Properties: Consider the required mechanical properties, such as strength, stiffness, and fatigue resistance, when selecting the alloy and temper.


The Ultimate Guide to Square Aluminum Extrusion is an essential resource for anyone involved in the design, manufacturing, or application of square aluminum extrusions. It provides a comprehensive understanding of the material, processes, and design considerations, enabling readers to make informed decisions and achieve optimal outcomes in their projects.
