Aluminum rectangular tube 6063-T52: 1x2x1/8, 2x3, 2x4, 1x1-1/2 sizes, wall and weight + STEP/STL — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/aluminum-rectangular-tube-6063-t52/ (sheet CC BY 4.0) Basis: Continental Steel 6063-T52 aluminum tube listings (size, wall, lb/ft, kg/m; sharp corners as stated); ABC Supply catalogue for the radius variants Catalog version: 2026-10-20 Overall (mm): length 101.6 - Aluminum rectangular tube in 6063-T52 (specification AMS-QQ-A-200/9 as listed), the extruded 'structural' hobby and fixture tube sold by McMaster-Carr, Online Metals and Metals Depot. Wall thickness 0.062 in is the nominal 1/16 in (1.5748 mm) and 0.125 in is 1/8 in; the distributor prints 0.062, not 0.0625. - Corner radius: the distributor listing (Continental Steel) states 'sharp inside and outside corners', so the files are hollow rectangles with square corners. ABC Supply's catalogue also lists radius-corner variants (for example 1 x 2 x .062 with a .140 R, 2 x 4 x .250 with .375 R), each one a separate item, so there is no standard radius to draw; if your tube has rounded corners, measure it. - Files: 20 sizes drawn as 4 in (101.6 mm) long extrusions along X, A across (y), B up (z), z = 0 on the bottom face. Weights are as printed. A check on every file: the printed kg/m divided by the drawn section area gives 2.68 to 2.69 g/cm3, aluminum density. - Nominal dimensions only: Aluminum Association tolerances on size, wall and straightness are not applied. The published sizes are the stock sizes of one distributor, not a closed standard list; other mills sell more. - McMaster-Carr has the aluminum tube per-part STEP files (linked, not copied). size (in) wall (in) outside A (mm) outside B (mm) wall (mm) weight (lb/ft) weight (kg/m) 1/2 x 1 0.125 12.7 25.4 3.175 0.3638 0.5414 3/4 x 1-1/2 0.125 19.05 38.1 3.175 0.582 0.8661 1 x 1-1/2 0.125 25.4 38.1 3.175 0.6548 0.9744 1 x 2 0.125 25.4 50.8 3.175 0.8003 1.191 1 x 3 0.125 25.4 76.2 3.175 1.0913 1.624 1-1/4 x 2-1/2 0.125 31.75 63.5 3.175 1.0185 1.5157 1-1/2 x 2 0.125 38.1 50.8 3.175 0.9458 1.4075 1-3/4 x 2-1/4 0.125 44.45 57.15 3.175 1.0913 1.624 1-3/4 x 3 0.125 44.45 76.2 3.175 1.3095 1.9488 1-3/4 x 4 0.125 44.45 101.6 3.175 1.6005 2.3818 1-3/4 x 4-1/2 0.125 44.45 114.3 3.175 1.746 2.5983 1-3/4 x 5 0.125 44.45 127.0 3.175 1.8915 2.8149 2 x 3 0.125 50.8 76.2 3.175 1.3823 2.0571 2 x 4 0.125 50.8 101.6 3.175 1.6733 2.4901 2 x 4 0.25 50.8 101.6 6.35 3.201 4.7636 2 x 5 0.125 50.8 127.0 3.175 1.9643 2.9232 2 x 6 0.125 50.8 152.4 3.175 2.2553 3.3563 3 x 5 0.125 76.2 127.0 3.175 2.2553 3.3563 3 x 6 0.125 76.2 152.4 3.175 2.5463 3.7893 4 x 6 0.125 101.6 152.4 3.175 2.8373 4.2224 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Continental Steel & Tube: Aluminum rectangular tubing, series 6063-T52 (AMS-QQ-A-200/9): size, wall, lb/ft, kg/m; sharp inside and outside corners — web — Publisher's page; dimensions are facts — https://continentalsteel.com/viewitems/aluminum-tubing-and-pipe/aluminum-rectangular-tubing - ABC Supply (aluminum tube catalogue pages): Square, radius-square and rectangular tube in 6063-T52 / 6061-T6, some with listed corner radii (e.g. .140 R) — web — Publisher's page; dimensions are facts — https://res.cloudinary.com/account-abcsupply-com/tci/catalogpages/Aluminum_Tubes_pgs32-35.pdf - McMaster-Carr: Aluminum 6063-T52 temper (square and rectangular tube are filed under aluminum) (free STEP/IGES per part, for your own design use; no redistribution) — STEP, IGES, PDF — McMaster-Carr site terms: personal design use, no redistribution [verify license at link] — https://www.mcmaster.com/products/t52-temper-aluminum Free files (CC BY 4.0, Xem Studio; STEP + STL, 20 parts): https://xemstudio.com/files/hardware/aluminum-rectangular-tube-6063-t52/index.json API: https://xemstudio.com/api/geometry?object=aluminum-rectangular-tube-6063-t52
