Export compliance note - 7075 & 2024 aluminum round bar. 7075 and 2024 are listed dual-use items under China's export-control catalogue, but control is dual-condition, not an across-the-board ban. It applies only to solid cylindrical bar (and tube > 75 mm OD) with an ultimate tensile strength of ≥ 460 MPa at 20 °C. Many tempers fall below this threshold; where it is met, export requires a PRC dual-use license and an eligible end-user. GNEE supplies 7075 and 2024 round bar to licensed buyers and can advise on documentation. For general fabrication and export without licensing, 6061, 6082 and 6063 cover most needs - ask us which grade fits your part.

Aluminum Round Bar Alloys and Tempers
The table below compares the five stocked grades by typical room-temperature mechanical values. These are reference figures from ASTM / EN / Aluminum Association data; the values on your mill test certificate are the ones that govern the shipment.
| Alloy / Temper | Ultimate tensile strength (MPa) | Yield strength (MPa) | Elongation (%) | Density (g/cm³) | Why buyers choose it |
|---|---|---|---|---|---|
| 6061-T6 | 310 | 276 | 12 | 2.70 | Balanced strength, weldability and machinability for general parts |
| 6082-T6 | 310 | 260 | 10 | 2.70 | Higher strength than 6061 for structural and load-bearing use |
| 6063-T6 | 215 | 170 | 12 | 2.70 | Fine surface for anodizing and decorative trim |
| 7075-T6 | 570 | 505 | 11 | 2.81 | Near-steel strength for high-stress, lightweight parts |
| 2024-T6 | 440 | 395 | 13 | 2.78 | High strength with good fatigue resistance |
Values are typical minimum / typical levels for the listed tempers; actual results vary by heat and section. 7075-T6 exceeds the 460 MPa dual-use threshold for solid bar - see the compliance note above. Confirm the exact temper and properties with your drawing and MTC.
Choosing the Right Aluminum Alloy for Round Bar
Selection is a trade-off, not a ranking. Match the grade to the dominant requirement: use 6061 where you weld or need the easiest machining; 6082 where the part carries load; 6063 where surface finish and anodizing matter more than strength, and - for export - any licensing step. Cost follows the same order: 6000-series is the economical default, 2000/7000-series carries a material and processing premium.
Aluminum Round Bar Sizes and Specifications
The diameter range for aluminum round bar depends on the alloy group. GNEE supplies bar from 5 mm up to 1000 mm across the stocked series, with cut-to-length and custom diameters to drawing. Lengths are 1–6 m as standard, supplied fixed, multiple, or sawn to your dimension.
| Alloy group | Tempers | Diameter range (mm) |

|---|---|
| Diameter | Ø 5–1000 mm by alloy group (see table above); non-listed sizes on request |
| Length | 1–6 m standard; cut-to-length and multiple lengths available |
| Form / shape | Round (solid); square, hex and flat bar on request |
| Surface | Mill finish standard; bright-drawn, polished or anodized on request |
| Standards | ASTM B211 (cold-finished), ASTM B221 / EN 755 (extruded), GB/T 3191 |
Ranges are orderable typical limits, not a standing stock guarantee. Final diameter, length, temper and tolerance are fixed by your confirmed drawing and reported on the mill test certificate.
Dimensional Tolerances and Straightness of Aluminum Round Bar
Tolerance depends on the manufacturing route and diameter. Cold-finished (drawn) bar holds the tightest diameter limits - for example ± 0.05 mm around 12.5–25 mm diameter per ANSI H35.2(M); extruded bar runs wider. Straightness for cold-finished bar is typically 2 mm per metre. Tell us the diameter and process and we quote the applicable class; for precision-ground bar, limits down to ± 0.01 mm can be arranged.
Aluminum Round Bar Weight Reference
Weight per metre helps estimate handling, freight and material cost. For aluminum (density ~ 2.70 g/cm³) the mass per metre is approximately:
Weight (kg/m) ≈ 0.00212 × d² (d = diameter in mm)
| Diameter (mm) | ~ Weight (kg/m) | Diameter (mm) | ~ Weight (kg/m) |
|---|---|---|---|
| 10 | 0.21 | 100 | 21.2 |
| 20 | 0.85 | 150 | 47.7 |
| 50 | 5.30 | 200 | 84.8 |
| 80 | 13.6 | 300 | 190.8 |
Calculated from density 2.70 g/cm³; actual weight varies slightly with alloy density (2.70–2.81 g/cm³ for the grades above) and tolerance. Use as an estimate, not a certified value.
Aluminum Round Bar Manufacturing Processes and Finishes
Extruded Aluminum Round Bar
Extruded bar is pushed through a die and is the economical route for standard diameters and longer lengths. Surface is mill finish as standard and diameter tolerance is wider than drawn bar. It suits structural, architectural and general machined parts where the tightest limits are not required.
Cold-Drawn Aluminum Round Bar
Cold-drawn (cold-finished) bar is reduced through a die after extrusion, giving tighter diameter tolerance, better straightness and a brighter surface. It is the preferred form for high-speed CNC turning and automatic lathes where consistent diameter and finish cut secondary operations. Available where the alloy and size support the process - confirm with your drawing.
Surface Finish and Secondary Processing for Aluminum Round Bar
Options include mill finish, bright-drawn, polished and anodized surfaces. GNEE also coordinates cut-to-length sawing, precision grinding and light CNC machining to drawing. These are order-specific services, not a default on every bar - tell us what the next operation needs and we confirm feasibility and tolerance.
Applications of Aluminum Round Bar
Aluminum Round Bar for CNC Machining
Machined components - valve bodies, hydraulic fittings, fasteners, shafts, bushings and instrument parts - are the largest use of our round bar. 6061 and 6082 give good chip control and stable dimensions; cold-drawn diameter and straightness reduce setup and scrap. Send the part drawing and we confirm alloy, diameter and tolerance.
Aluminum Round Bar for Structural and Industrial Components
6082 and 6061 round bar are used for gear blanks, guide rods, spacer sleeves, conveyor rollers and machine frames where strength and corrosion resistance matter without the weight of steel. We confirm the load case and environment so the temper and size are right.
Aluminum Round Bar for Automotive and Transport Components
Lightweight suspension, drivetrain and aftermarket parts use 6061/6082 for mass saving; 7075 is specified where strength-to-weight is critical (subject to the export-compliance note above). We supply to drawing and can arrange machining for non-safety-critical components.
Aluminum Round Bar for Marine and Corrosion-Exposed Service
6061 and 6082 resist atmospheric and mild marine exposure and are common for railings, deck fittings and architectural hardware. For continuous seawater immersion, alloy and design must be confirmed case by case - tell us the environment and we advise.
Aluminum Round Bar Standards and Quality Inspection
Applicable Standards for Aluminum Round Bar
Standard selection follows the product form and process, not the name alone. ASTM B211 / B211M covers cold-finished (drawn) aluminum bar, rod and wire; ASTM B221 / B221M covers extruded bar, rod, wire, profiles and tube; EN 755 is the European series for extruded rod and bar; GB/T 3191 applies to Chinese domestic supply. We match the standard to the form you order and state it on the MTC.
Chemical Composition and Mechanical Testing of Aluminum Round Bar
Each heat is reported by the mill for chemistry and mechanical properties (tensile, yield, elongation) in the EN 10204 3.1 certificate. We do not claim every batch is independently tested beyond what the mill reports; where you need witnessed or third-party testing, we arrange SGS / BV or your nominated inspector.
Dimensional and Surface Inspection of Aluminum Round Bar
Before packing we verify diameter, length, straightness and surface condition against the order. Out-of-roundness and end-squareness are checked on request. Results feed the inspection record that travels with the shipment.
Mill Test Certificates and Traceability for Aluminum Round Bar
Every consignment ships with an EN 10204 3.1 mill test certificate carrying the heat number, composition and mechanical values, so material is traceable to the cast. EN 10204 3.2 certificates and third-party inspection reports are available on request - state the requirement when you inquire so it is built into the plan.
Aluminum Round Bar Supply and Processing Capabilities
Stock and Order Coordination for Aluminum Round Bar
GNEE holds common alloys, tempers and diameters in stock and produces custom sizes to drawing, including mixed multi-line orders in one shipment. We coordinate cutting, light machining and inspection so you receive bar close to your net shape. Send the full list - alloy, temper, diameter, length and quantity per line - and we quote it as one order.
Export Packaging and Delivery Planning for Aluminum Round Bar
Bars are bundled, end-protected and moisture-wrapped, with labels showing heat number, diameter, length and weight; paper interleaving is used where surface protection matters. Bundles are secured for sea freight and packed to avoid mix-up between alloys and sizes. Documents - packing list, commercial invoice, bill of lading and mill test certificates - are prepared for customs clearance, and packing photos can be shared before loading.
Aluminum Round Bar Pricing, Packaging and Lead Time
Factors Affecting Aluminum Round Bar Price
Price is built from the aluminum base plus alloy and process factors: the grade and temper, diameter and length, quantity, manufacturing route (extruded vs cold-drawn), tolerance and surface requirements, any machining or inspection service, and packaging and Incoterms. GNEE benchmarks the metal base to SMM (Shanghai Metals Market) and quotes a project-based price rather than a fixed list price, because alloy and size change the number materially. Send your spec for a current quote.
Lead Time and Minimum Order Quantity for Aluminum Round Bar
Typical lead time is 15–30 days after order confirmation; stock items ship sooner. MOQ is flexible - both small trial orders and large-volume / full-container orders are accepted, and larger volumes are welcome. Exact dates are confirmed against the current production schedule when you place the order.
FAQ
What aluminum alloys are available in round bar form?
GNEE stocks 6061, 6082, 6063, 7075 and 2024 round bar, with other grades (e.g. 2014, 5052, 2011) available on request. Temper and size for each must be confirmed against your drawing - not every temper is offered in every diameter.
What diameters and lengths can I order?
Standard supply is Ø 6–300 mm and 1–6 m long, with cut-to-length and custom diameters to drawing. Smaller and larger diameters are handled case by case. Tolerance and straightness depend on the process and are confirmed at order review.
What is the difference between extruded and drawn aluminum round bar?
Extruded bar is die-pressed and economical, with mill-finish surface and wider tolerances; cold-drawn bar is reduced after extrusion for tighter diameter, better straightness and a brighter surface, suited to high-speed machining. The right route depends on your tolerance and finish needs.
Which standard applies to aluminum round bar?
It depends on form and process: ASTM B211 for cold-finished bar, ASTM B221 and EN 755 for extruded bar, GB/T 3191 for domestic Chinese supply. We state the matched standard on the mill test certificate rather than assuming one for all bars.
Can I request a material test certificate?
Yes. Every shipment includes an EN 10204 3.1 mill test certificate with heat number, chemistry and mechanical values. EN 10204 3.2 and third-party inspection (SGS / BV) are available on request - tell us at inquiry so they are planned in.
What information is needed for a quotation?
Send alloy and temper, diameter, length, quantity (per line for mixed orders), required standard, any surface or machining requirement, and the destination. We confirm alloy selection, packing, inspection and 15–30 day lead time together.
Are 7075 and 2024 aluminum round bars export-controlled?
They are dual-use listed, but control triggers only for solid cylindrical bar (and tube > 75 mm OD) at UTS ≥ 460 MPa at 20 °C. Many tempers fall below that; where it applies, a PRC export license and eligible end-user are required. GNEE supplies them to licensed buyers and can advise - 6061/6082/6063 cover most export without licensing.
