CUT-TO-SIZE METAL
6061 Aluminum Square Bar
Specify solid aluminum square bar with a 6061 grade reference. Give side size, cut length and requirements for machined blocks, spacers or fabricated details.
Attach a PDF, DXF or STEP file. You can request a review without configuring individual pieces.
How your quote works +
Add one or more cuts, share your requirements and tell us where to deliver. We review material, cutting and freight before sending a quote.
Dimensions & material weight +
Dimensions describe your requested section and cut length. Standard sections and feasible cuts are confirmed during review. Include any tolerance in project details. Weight is theoretical, uses ideal section geometry and excludes corner radii, packaging and cutting loss. The preview is a schematic, not a manufacturing drawing.

What to include in your request
If the finished component must be square, flat or closely sized, put those requirements on a drawing and allow for the intended machining.

01
Flat exterior faces are part of the starting geometry
Square bar gives a mounting block or spacer four flat nominal side faces and an equal-sided envelope. That can be useful when the finished component retains flats rather than becoming entirely round. The stock still does not define the final reference system: a block resting on two machined faces has different requirements from a decorative block retaining all four sides. Thinking about which faces survive the process explains why two parts with the same outside size may need different blank and finish instructions.
02
Multiple-face machining needs shared references
A hole entering one face and a pocket opening through another must relate to each other inside the finished block. Separate views become a complete description when they share a reference system. This matters when a short blank is repositioned during machining: its stock corner is not automatically the final datum. A designated base and reference side make the relationships clear, while a separate visible-face description prevents cosmetic requirements from being confused with the surfaces used to locate or measure the part.
03
Compare equal-sided and unequal-sided blanks
Square bar is easiest to compare with flat bar and plate by looking at the finished envelope. If one side is much smaller than the other, a rectangular blank may reduce unnecessary stock around the part. If the final component is predominantly cylindrical, round bar may simplify the starting shape instead. Keep the comparison attached to the machining drawing and include any required raw form, because equal overall volume does not make different stock shapes interchangeable for workholding or locating.

PUT THE DIMENSIONS INTO PRACTICE
Example: a four-piece square bar request
Use this illustrative cut line to see how the fields work. It is a dimensional example, not a stock listing or a recommended section for a particular load.
Side size1 in25.4 mm
Cut length12 in304.8 mm
The side size is 1 in, so the ideal solid cross-section is 1 square inch. A 12 in length contains 12 cubic inches of material. The two section dimensions are equal; the third number is length, not a second side size.
How the theoretical weight is calculated
Cross-sectional area × cut length × reference density = estimated material weight.

Four pieces, approximately

Calculated from ideal geometry and a reference density. Actual section, alloy, tolerances, cutting loss and packaging can change the result. This is not a shipping weight or a load rating.
On your own cut list, add a part reference and quantity to each distinct size. Put extra operations such as holes, miters, threads or finish work on the drawing, then keep that drawing reference with the relevant line.
No. This family is solid. Use aluminum square tube for a hollow section and specify both its outside side size and wall thickness.
Can square bar replace a plate-cut block?
Possibly, but compare the required alloy, condition, available dimensions and machining allowance. Indicate whether either stock form is acceptable for your drawing.
Does the 6061 reference also choose the temper?
No. Include the required temper in the condition or notes field. The grade reference alone does not define the complete material condition.
Why choose a square blank for a component with exterior flats?
The starting envelope already includes four flat nominal sides, which may align with faces retained in the finished part. Round stock would require those flats to be created later. The useful comparison is the complete machining route, including which surfaces remain and how the part is held.
Should all six faces of a short block be machined?
That decision comes from the part requirements. Identify the locating, mating and visible faces, then let the machining plan define which need preparation. A request to machine every face can be unnecessary if some surfaces have no finished tolerance or cosmetic requirement.
What does a datum mean on a machined square block?
A datum belongs to the reference system used to locate or assess finished features. It is not simply any convenient stock corner. A designated base and side can relate holes on different faces, while a presentation-face note describes appearance rather than that dimensional reference.
Can I use the stock corner as the origin for a machined feature?
Show the intended reference system on the drawing and state whether its surfaces are raw or machined. A nominal stock corner is not a complete machining datum specification. The machinist needs to know how the reference will be established before locating the feature.
What should I send for a block with holes entering adjacent faces?
Provide enough views to show each hole axis, depth and relationship to the others. Include a section where holes intersect or where the internal shape is otherwise unclear. A single top view and an overall stock size can leave important machining details ambiguous.
Why is equal stock volume an incomplete way to compare blank shapes?
Different shapes put material in different locations and provide different clamping surfaces. Equal-volume round, square and rectangular blanks may therefore support different machining routes. The relevant blank must contain every finished feature and the allowance needed by the selected process, not just a similar amount of metal.
What dimensions do I need to request 6061 aluminum square bar?
Provide side size, cut length, plus quantity for each size. Use inches or millimeters consistently. Add the required grade, condition, finish and any critical tolerances; attach a drawing for details the standard fields cannot describe.
