The best choice depends on what “3/4 aluminum angle” means for your project: a 3/4-inch leg, a 3/4-inch thickness, or a 3/4-inch-wide angle. The products below include one 3/4-inch-wide option and four larger 3-inch-by-3-inch angles; none is listed as 3/4-inch thick. Check the dimensions before ordering. For compact trim or small brackets, the Blulu angle is the closest match. For heavier stock, the 6061 options offer thicker 1/4-inch material.
| Product | Listed dimensions | Best for |
|---|---|---|
| Blulu 6063 angle | 20mm × 20mm × 3mm; 24 inches long | Narrow angle and longer pieces |
| YLJNGUS 6061 angle | 3 × 3 × 1/4 inches; two 12-inch pieces | Two short, thick pieces |
| CNQLIS 6061 angle | 3 × 3 × 1/4 inches; one 12-inch piece | Single short piece |
| 13-inch 6061 angle | 3 × 3 × 1/4 inches; 13 inches long | A slightly longer short piece |
| Randall 6063-T6 angle | 3 inches wide × 1/8 inch thick; 36 inches long | Longer architectural-style stock |
Blulu 6063 Narrow Aluminum Angle
Best for: Projects needing a narrow, relatively long angle rather than a heavy 3-inch-by-3-inch profile. The listing describes two pieces, each 24 inches long, made from corrosion-resistant 6063 alloy. It gives actual metric dimensions of 20mm × 20mm × 3mm, approximately 0.79-inch legs and 0.12-inch thickness.
This is the closest listed option for someone searching for a small aluminum angle, but it is not exactly 3/4 inch wide or 3/4 inch thick. It may be cut to length, according to the product details. The listing also cautions that surface scratches may be present, and notes a dimensional tolerance.
YLJNGUS Two-Piece 6061 Angle
Best for: Buyers who need two substantial short pieces for brackets, frames, or shop projects. Each listed piece measures 3 × 3 inches across the legs, is 1/4 inch thick, and is 12 inches long. The product details describe 6061-T6 aluminum and say the material can be cut, drilled, welded, or machined.
Choose this if the project calls for thick, equal-leg stock and a two-piece pack. Its dimensions do not match a 3/4-inch leg or thickness, so avoid it if that measurement is essential. The listing makes corrosion-resistance claims but does not specify a particular finish.
CNQLIS Single 6061 Angle
Best for: A project requiring one 12-inch length of 3 × 3 × 1/4-inch angle stock. The product is described as 6061 aluminum, with equal 3-inch legs and a 1/4-inch thickness. Those dimensions make it a better fit for a thick bracket or structural-style DIY component than for narrow trim.
The listing emphasizes lightweight handling and corrosion resistance for indoor and outdoor applications. Consider the size carefully: despite appearing in a search for 3/4 aluminum angle, the listed legs are 3 inches long. It is a single-piece option, not a multi-piece pack.
13-Inch 6061 Aluminum Angle Stock
Best for: Buyers who need a short piece slightly longer than a foot. This listing specifies 3 × 3-inch legs, 1/4-inch thickness, and a 13-inch length. It identifies the material as 6061 aluminum and describes machine-cut edges with a smooth, burr-free surface.
The product details mention corrosion resistance, weldability, and oxidation resistance. This is another large-profile option, not a 3/4-inch angle. Its single 13-inch length may not suit projects requiring longer continuous stock or multiple pieces.
Randall 36-Inch 6063-T6 Angle
Best for: Projects needing a longer 36-inch piece of architectural-style aluminum angle. The listing gives a 3-inch width and 1/8-inch thickness, with equal legs and a 90-degree angle. It identifies the alloy as 6063-T6 and describes uses such as framing, bracketing, sign frames, and corner guards.
This is better for longer runs than the short 6061 pieces, but its 3-inch width is not a 3/4-inch leg. The listing says the angle has no inside radius; confirm that this profile detail works with your design.
Buying Guide: How To Choose Aluminum Angle
What does “3/4 aluminum angle” mean?
Angle stock is commonly described using leg length and material thickness. A search phrase such as “3/4 aluminum angle” can refer to a 3/4-inch leg, a 3/4-inch thickness, or a specific profile sold under that shorthand. These listings do not include a 3/4-inch-thick product. Blulu is the closest option to a small angle, with approximately 0.79-inch legs and 0.12-inch thickness; verify the required dimensions against your plan.
Should you choose 6061 or 6063?
The listed 6061 products are 1/4-inch-thick, short stock, and are described for machining or fabrication. The 6063 options include the narrow Blulu pieces and the 36-inch Randall angle. Compare the alloy, temper, dimensions, and stated intended uses rather than assuming products are interchangeable.
How much length and thickness do you need?
Measure both legs, material thickness, and total length. A 1/4-inch-thick 3-inch angle is substantially different in profile from a roughly 1/8-inch-thick angle with legs under an inch. Select a longer piece when the design requires fewer joints; choose short stock when a small component or limited cut length is sufficient.
What should you check before ordering?
Confirm whether dimensions are listed in inches or millimeters, how many pieces are included, and whether cutting or surface imperfections matter for your application. For a close-fit assembly, allow for the dimensional tolerance mentioned in the listing. Do not rely on the search term alone: compare the stated measurements with the drawing or hardware specification.
Frequently Asked Questions
Is any listed product 3/4 inch thick?
No. The products list thicknesses of 1/4 inch, 1/8 inch, or 3mm. None is listed as 3/4 inch thick.
Which option is closest to a 3/4-inch leg?
Blulu lists actual dimensions of 20mm × 20mm, approximately 0.79 × 0.79 inches, with 3mm thickness. It is close in leg size but not an exact 3/4-inch match.
Which product is the longest?
The Randall angle is listed at 36 inches long. The Blulu pieces are 24 inches long each.
Which options are 1/4 inch thick?
The YLJNGUS, CNQLIS, and 13-inch 6061 listings each specify 1/4-inch thickness.
Can aluminum angle be cut or drilled?
The YLJNGUS listing specifically says its angle can be cut and drilled. For other products, check the listing details and use appropriate tools and safety precautions.
