This article presented a brief summary of common aluminum tubing shapes and dimensions. While these alloys are commonly associated with the aerospace industry, it is important to note that their applications extend beyond that field. Table 1 - Standard Aluminum Tubing Sizes and Key Dimensions 7075-T-T3 are widely recognized as the top choices when it comes to high-strength aluminum alloys for tubing applications. Square and rectangular tubing are used primarily for structural and architectural purposes.

Not all sizes are available off-the-shelf and some sizes will be available only as mill orders. Most tubes are available in stock lengths while some of the smaller round sizes may also be furnished coiled in longer lengths. It can be cold bent, and has a high difference between tensile strength. Materials Tensile Strength Comparison (approximate psi) 5052 Aluminum 30,000 Mild steel tube (HREW) 40,000 6061 Aluminum 45,000 Black iron pipe 47,000 304. The following table presents some common tubing sizes for round, rectangular, and square profiles. 3003 aluminum is the best for bending due to its midrange strength and high elongation. It can be bent using a variety of methods, including hand bending, press braking, and hydraulic tube bending. Some rectangular shapes are available with radiused corners. Aluminum is a soft, malleable metal that is relatively easy to work with. It is specified by outside diameter and wall thickness or inside diameter, or, by stub gauge, for round tubing, and by leg length and wall thickness for rectangular tubing. Aluminum tubing is drawn or extruded and is available as round and rectangular shapes.
