Aluminum extrusion is the process used to transform aluminum alloy into an infinite assortment of functional products. Making the most of aluminum’s light weight and malleability, the extrusion process creates shapes by heating a billet, or cylindrical log, of aluminum alloy to soften it and then forcing it under high pressure through a special steel die using a hydraulic press or ram. The end result is a piece of aluminum that will maintain the specific shape of the die.
Commonly produced shapes include angles, tubing, and channels, and can be customized to very close tolerances for numerous types of applications. Extruded aluminum shapes can be found in automotive, aviation and construction parts, domestic appliances, computers, architectural components, and a wide variety of products, including window frames, railings and bicycles. These shapes can range in size from one millimeter to several feet long.
The process of aluminum extrusion results in very durable parts and shapes. Aluminum has excellent corrosion resistance and is very flexible. It can be joined through the use of soldering, welding, or brazing. Aluminum’s heat conductivity makes it ideal for use in products that provide heat shielding or heat transfer. The surface of the extruded aluminum parts can also be finished in a variety of ways which makes it architectural aluminum perfect for architects, including anodizing, painting and powder-coating, to give the product a particular appearance or to accommodate specific performance requirements.

Extruded Aluminum Shapes
Extruded aluminum is available in a vast array of shapes and sizes including basic bars, channels, angles, schedule 40 pipe and round, square and rectangular tubes. Extruded aluminum shapes also include angles, bars, corner extrusions, channels, division bars, decorative mirror trim, sliding t-track, J channel, F channel and H or Z channel. This vast array of choices makes extruded aluminum shapes appropriate in the manufacture of boat and RV moldings, counter edging, sign frames and handrail fittings.
Architectural Aluminum Angle
Extruded architectural aluminum angle is used in applications where appearance is more important than strength. It has a sharp, 90 degree angle on the inside and outside corners where the two legs meet and is a constant thickness to the very end of the piece.
Aluminum Extrusion Shapes
Aluminum is dense, light weight, and extremely ductile and malleable, permitting it to be stretched and shaped without cracking or breaking. In fact, aluminum is the second most malleable metal (after gold), and the seventh most ductile. These exceptional properties allow aluminum alloy to be transformed via the extrusion process into an unlimited number of durable parts and shapes. Aluminum extrusion shapes include basic rods, bars, pipes, open seam square and rectangular tubing, structural angles, corner extrusions, I-beams, H-beams, sliding t-track, as well as U-channel, J-channel, C-channel, hat channel, Z-channel, and virtually any imaginable shape.
