Aluminum square tube 6063-T52: 1x1x1/16, 1x1x1/8, 1-1/2 sq, 2 sq sizes, wall and weight + STEP/STL — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/aluminum-square-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 square 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: 17 sizes drawn as 4 in (101.6 mm) long extrusions along X, centred on y = 0, 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) 3/4 sq 0.062 19.05 19.05 1.575 0.1986 0.2955 3/4 sq 0.125 19.05 19.05 3.175 0.3638 0.5414 1 sq 0.062 25.4 25.4 1.575 0.2708 0.403 1 sq 0.125 25.4 25.4 3.175 0.5093 0.7579 1-1/4 sq 0.125 31.75 31.75 3.175 0.6548 0.9744 1-1/2 sq 0.125 38.1 38.1 3.175 0.8003 1.191 1-3/4 sq 0.125 44.45 44.45 3.175 0.9458 1.4075 2 sq 0.125 50.8 50.8 3.175 1.0913 1.624 2 sq 0.25 50.8 50.8 6.35 2.037 3.0314 2-1/2 sq 0.125 63.5 63.5 3.175 1.3823 2.0571 3 sq 0.125 76.2 76.2 3.175 1.6733 2.4901 3 sq 0.25 76.2 76.2 6.35 3.201 4.7636 4 sq 0.125 101.6 101.6 3.175 2.2553 3.3563 4 sq 0.25 101.6 101.6 6.35 4.365 6.4958 5 sq 0.125 127.0 127.0 3.175 2.8373 4.2224 6 sq 0.125 152.4 152.4 3.175 3.4193 5.0885 8 sq 0.188 203.2 203.2 4.775 6.8381 10.1762 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Continental Steel & Tube: Aluminum square 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-square-tubing-series-6063-t52 - 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, 17 parts): https://xemstudio.com/files/hardware/aluminum-square-tube-6063-t52/index.json API: https://xemstudio.com/api/geometry?object=aluminum-square-tube-6063-t52
