2 February 2024, Maharashtra: The cross-sectional profile is required to form the metal-heated aluminium alloy billets that are forced through a die to make aluminium extrusions. Because of their strength, resistance to corrosion, and machinability, 6063 and 6061 are the most often used aluminium alloys for extrusions. A range of fundamental cross-sectional shapes, including tubes, angles, channels, I-beams, and T-shapes, are available for standard extrusion profiles.

Angle bars, C-channels, U-channels, square tubing, and rectangular tubing are a few of the most commonly used conventional extrusion profiles. When strength is needed for framing, shelves, or structural applications, rectangular tubing's hollow shape is perfect. Similar in design but with corners rather than curving edges, square tubing profiles are ideal for modular buildings. Angle bars are L-shaped pieces that are frequently utilized as support components, bracing, and frame connectors. Versatile structural shapes with one or both sides folded inward include C-channels and U-channels.

The structural qualities and ease of joining of standard extrusion profiles make them popular choices. For instance, to make stiff frames and structures, angle bars are commonly bolted or welded at the corners. C-channels can be used to reinforce shear walls or butted together end to end to provide continuous framing. To put together face frames or enclosure panels, U-channels are frequently nestled together. The consistent shapes of standard extrusions make it possible to fabricate them simply and repeatedly with common tools.

Standard aluminium extrusion profiles are widely used as framing for windows, doors, curtain walls, storefronts, awnings, and signage in the building sector. They are ideal for these outdoor applications due to their lightweight and resistance to corrosion. Square and rectangular tubing are frequently used to make the framework for modular constructions. In roofing, angle bars, and C-channels are frequently utilized as purlins, bracing, and structural supports.

Numerous transportation uses are also made possible by standard extrusion profiles. Extruded aluminium is being utilized more often in the automobile industry for vehicle bodies, closures, and chassis to reduce weight. Square tubing is frequently utilized for roll cages in recreational equipment and racing cars. Trailer and equipment frames frequently use C-channels and angle bars. Extruded aluminium is used in the aircraft industry to create airframes, wings, and other vital load-bearing components.

Standard aluminium extrusions are essential to a wide range of industrial products and machines, extending beyond building and transportation. Common uses include ladders, handrails, enclosures, modular storage and racking systems, and structural frameworks for equipment. Square and rectangular tubing are commonly utilized as structural support elements. Angle bars are frequently used to strengthen tooling and machine frames. For linear motion systems, C-channels and U-channels are frequently used as track profiles.

Numerous consumer and business goods are also made possible by standard aluminium extrusion profiles. Signage and displays, workout equipment, window and door frames, furniture frames, and modular displays are a few common examples. Extruded aluminium is a great material for durable and portable items because it combines strength and lightweight. The modular assembly of interchangeable components is made possible by their uniform forms.

Whether utilized as modular building blocks or load-bearing structures, conventional aluminium extrusion profiles offer strength, adaptability, and design freedom for various applications. Their ability to withstand corrosion and form through extrusion manufacturing makes it possible to produce complex profiles in large quantities at a reasonable cost. Standard aluminium extrusions will continue to be an essential enabling technology as product designers continue to innovate with new materials.

Standard aluminium extrusion profiles can be made more functional with finishing and surface treatments. Mill finish is a common finish that keeps its brilliant metallic sheen soon after extrusion. For applications where corrosion resistance is not required, this is perfect. Anodizing protects aluminium from corrosion by coating its surface with a solid oxide layer that makes colour dyeing possible. Powder coating provides long-lasting colour possibilities by using baking to fuse the textured, coloured powder to the surface. Extrusions used for decorative and outdoor uses are frequently anodized or powder-coated.

To incorporate functional components, extruded aluminium profiles can also be machined and tooltied. The processes of cutting, drilling, tapping, and milling enable the insertion of complex geometries, holes, and slots into standard shapes. For instance, mounting tabs can be machined into rectangular tubing, and pivot or hinge elements can be milled into angle bars. Aluminium extrusions can be bent to increase their potential applications. To construct more intricate frame connections, C-channels and angles can be bent into compound angles. Extrusions can also be made to fit into compound radius or curved constructions by bending them.

Highly tailored aluminium extrusions beyond typical profiles are now possible thanks to developments in computer-aided design and manufacturing. Extrusion with near-net shape enables the creation of sophisticated 3D geometries, undercuts, and complex shapes in a single piece. Several profiles and forming processes are used in multi-stage extrusion to produce hybrid cross-sections with internal cavities or nested features. For functional integration, co-extrusion combines two or more aluminium alloys at a time. With extruded aluminium, these specific capabilities keep pushing the limits of engineering and design.
