Aluminum square bar products are manufactured by heating a square ingot of aluminum, passed through rolls into coil shapes, and then reheated to extrude the material and create the square shape. It can be manufactured into a variety of sizes and widths. A square bar is an aluminum bar with four equilateral sides.

Aluminum bar stock is available in square, round or rectangular extrusions in a variety of sizes. Please call 800-826-3370 for aluminum flat bar prices and stock availability.

This kind of bar product is ubiquitous today, with dozens of different applications in electrical applications, airplane structural components, structural support, transportation, decorative pieces connecting pieces of machinery, automotive parts, and even computer parts. You might notice it most commonly as support pieces for furniture at home.

The 2024 alloy uses copper as the primary alloying element, which makes the aluminum alloy stronger and gives it good fatigue resistance. 2024 is known as the “aircraft alloy” because it is most commonly used in the aerospace industry, especially for structural components. It is also seen in high-performance cars.

The 6061 alloy flat bar is useful in applications where corrosion resistance is critical and the material needs to be light. It is most commonly used in fabrication or structural projects, including the frames of furniture, supporting beams, and shafts. Because of its corrosion resistance, it is also suitable for marine uses.

The 7075 alloy has one of the highest strengths of all aluminum alloys. It has an average response to welding and being machined. Its most common application is in aviation and marine settings where its strength supports critical components, as well as missile components.
