Aluminum round tube (6061-T6) OD × wall and aluminum pipe Schedule 40 / 80: sizes, ID, weight + 100 mm tube sections — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/aluminum-round-tube-and-pipe-6061-6063/ (sheet CC BY 4.0) Basis: Four distributors' round tube lists (Continental Steel & Tube, Online Metals, Alcobra Metals, Russel Metals) and two pipe sources (Metals4U, Continental Steel); pipe walls compared with the ASME B36.10M figures already on steel-pipe-asme-b36-10m-nps-1-8-to-24 Catalog version: 2026-10-20 Overall (mm): length 101.6, width 101.6, height 100.0 - Aluminum round tube is sold by OD and wall (inches) in 6061-T6 (Continental also lists T6511, the stress-relieved extrusion temper) and, on some distributors' pages, 6063. The table is the union of four lists, 84 OD × wall sizes; the last column shows who lists each size (CS Continental Steel & Tube, 25 of 44 items read; OM Online Metals, two pages of 25 read; AL Alcobra Metals, 10 items; RM Russel Metals, 19 sizes). A size missing from the page-1 lists is not evidence that it is not made. - ID is OD − 2 × wall. Continental prints an ID and a weight (lb/ft) for each row; every printed ID, and the three IDs Online Metals prints for sizes also listed elsewhere, equal OD − 2 × wall to within 0.001 in (checked here). Continental's weights follow (OD − wall) × wall to within 1 % (a check made here). Russel prints weights too (omitted: they are rounded differently, for example 1/2 × 0.065 at 0.104 lb/ft). - Aluminum pipe is made to the same nominal pipe sizes and schedules as steel pipe (ASME B36.10M OD and wall); the distributors' walls below are compared with the B36.10M figures on steel-pipe-asme-b36-10m-nps-1-8-to-24. Differences, shown not resolved: Metals4U prints Sch 40 walls of 0.07 for 1/8 in and 0.090 for 1/4 in where the B36.10M page has 0.068 and 0.088, and an OD of 0.41 for 1/8 in where B36.10M has 0.405. Left out as a listing error: Metals4U's '4 in' Sch 40 row, which repeats the 3 in OD (3.500), wall and ID; its listing also has no 5 in. Its '3-1/2 in' row (OD 4.000, wall 0.226, ID 3.548) equals B36.10M. Continental's Sch 80 2-1/2 in row prints an ID of 1.323, but OD 2.875 − 2 × 0.276 is 2.323, so the ID shown here is the derived 2.323 (the printed wall 0.276 equals B36.10M's). Its 3 in row prints the OD as '3 1/2' (3.500). - Pipe weights (lb/ft) are Metals4U's aluminum column, shown only where its pipe chart prints them (Sch 40 1/4, 3/8, 1/2, 3/4; Sch 80 1/2, 3/4). - Files: 100 mm hollow sections of every round tube size that at least two distributors list. Aluminum pipe is not drawn again: it has the same OD and wall as steel pipe, whose sections are on steel-pipe-asme-b36-10m-nps-1-8-to-24 (scale the material, not the geometry). The length is Xem's example length.
