Notes

• Flat bar: the 64 thickness x width sizes of Russel Metals' 6061-T6 aluminum flat bar table (extruded rectangle bar, 1/8 x 1/2 up to 1-1/4 x 3) with weight per foot as printed. Remington Industries lists the option set thickness 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 1 in by width 1/2, 1, 1-1/2, 2, 2-1/2, 3, 4, 6, 8 in (which combinations are stocked is not stated); 'yes' in column 7 means both the thickness and the width are in Remington's option set, not that the combination is stocked. Sizes outside Remington's set (3/16 thickness, 5/8 and 1-1/4 widths) are Russel-only.
• Weights: each Russel weight was recomputed from the section at 0.0975 lb/in³ (2.70 g/cm³) as a sanity check. All but three agree within 3 %. Russel's 1/2 x 1-1/4 (0.785, section 0.731 and between 0.587 and 0.881 for its neighbours 1/2 x 1 and 1/2 x 1-1/2), 3/4 x 6 (4.391) and 3/4 x 8 (5.287) do not: the section gives 5.27 and 7.02 lb/ft, and 4.391 is also lower than 3/4 x 4 (3.524) scaled by 1.5 (5.29). The 3/4 x 6 and 3/4 x 8 weights look misplaced on that page (5.287 ≈ the 3/4 x 6 section weight), so all three are flagged, not corrected; the sizes themselves are kept.
• Round bar: Russel Metals' 6061-T6 round bar table, 37 diameters from 1/4 to 10 in with weight per foot (all within 3.5 % of the section weight). Remington's 'round rod' list is 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, 7/8, 1, 1-1/8, 1-1/4, 1-3/8, 1-1/2, 1-3/4, 2 in (14 sizes, all on Russel's list); Online Metals' listing titles name 3/4, 1, 1-3/8, 1-3/4, 1-7/8, 2-1/2, 2-3/4, 3-1/2, 4 and 6-1/2 in (6061-T651 cold finish or T6511 extruded; the 6-1/2 in is not on Russel's list; one more listing is named '14', which is not read as a size). Russel also lists 2011-T3 free-machining round bar in 1/8 to 2 in (31 sizes, not tabulated here).
• Tolerances, lengths (Remington lists lengths of 1 to 48 in cut-to-length) and tempers beyond the ones named are not tabulated. 1018 steel and 6061 square aluminum bar: bar-stock-sizes-round-square-steel-aluminum. Stainless: stainless-steel-round-and-flat-bar-sizes.
• No STEP/STL: round and rectangular bar are plain cylinders and boxes.
