# Aluminum angle stock sizes (6061-T6, 6063-T52) and inside / leg radii: 124 listed rows, 1/2 x 3/8 to 8 x 8 (distributor lists)

> What sizes does aluminum angle come in, and what is the fillet radius of aluminum angle?

- Category: Hardware › Materials & stock
- Kind: Standard part

## Notes

- Two lists: (1) Metal Supermarkets' 'aluminum angle, commonly used' stock list: the page has 125 rows of leg x leg x thickness with alloy, 6061-T6 or 6063-T52; the text extraction returned 124 of them, so one row is missing and the list is a sample of what one shop stocks, not a standard. 'quote only' means the page shows 'contact us' instead of 'add to cart'. 6063-T52 rows are the architectural sizes (0.065 to 0.25 thick), 6061-T6 the structural sizes. Metal Supermarkets prints no weights and no radii. Continental Steel's series 6061 angle page lists 328 items (first 25 read: 1/2 x 1/2 x 0.063 up to 3 x 3 x 0.313, all 6061-T6511, T6 or O) and agrees on the sizes it shows that overlap (1 x 1 x 1/8, 1-1/2 x 1-1/2 x 1/8, 2 x 2 x 1/4); it uses other thicknesses too (0.062, 0.094, 0.313).
- (2) The last 14 rows: Online Metals prints 'Inside Radius' and 'Leg Radius' on each product page. Read here for 14 sizes. The inside radius is the root fillet between the legs; 'leg radius' is not defined by Online Metals (which corner of the leg tip, one or both) and for 1/8 in legs it equals the thickness. The 2 x 2 x 1/4 page prints leg radius 0.25 where its 3/16 and 3/8 siblings print 0.125 and the 1/4 in 1.75 x 1.75 and 2 x 1.5 print 0.125: treat that one as unconfirmed. Every Online Metals page says the data is for reference, not design. The 2 x 3 and 2 x 2.5 product pages print the long leg first as '3 x 2' and '2.5 x 2' here.
- Because the tip-radius corner is not defined and only one distributor prints the radii (no second source), no angle profile is drawn. Equal-leg and unequal-leg Aluminum Association angles with weight and area, 59 sizes: aluminum-angles. Steel angle radii are printed by AISC and EN 10056: aisc-l-angles, en-10056-equal-angles.
- Weights on the Online Metals pages agree with the Aluminum Association weights on aluminum-angles where both exist (2 x 2 x 1/4: 1.13 vs 1.11 lb/ft; 1-1/4 x 1-1/4 x 1/8: 0.35 vs 0.35; 2 x 2 x 3/8: 1.59 vs 1.607 for 0.375 on that page).

## Questions

**What is the inside radius of 2 x 2 x 1/4 aluminum angle?**

Online Metals prints 0.25 in inside radius for 2 x 2 in angle in 1/8, 3/16, 1/4 and 3/8 thickness; its leg radius is 0.125 in (0.25 on the 1/4 in page, which looks like an outlier).

**What is the difference between 6061 and 6063 aluminum angle?**

In the stock list read here the structural sizes (1/8 in and up, to 8 x 8 x 1/2) are 6061-T6 and the thin architectural sizes (0.065 to 0.25) are 6063-T52; many sizes are listed in both.

**What is the biggest aluminum angle in the list?**

8 x 8 x 1/2 in, 6061-T6 (Metal Supermarkets); Online Metals also sells 8 x 8 x 3/4.
