Two buyers can quote the same alloy — 6061 T6 aluminum bar — and land on very different prices. The gap is rarely the metal itself; it is the form, specification and fabrication path. This page puts numbers on that spread so procurement can budget from the extruded base upward.
Reference base: standard extruded 6061 T6 round bar, Ø20–80 mm (ASTM B221), SMM-benchmarked at 26.9–27.9 RMB/kg (≈ USD 3.8/kg at an indicative FX of 7.10). All premiums below are measured against that base and are indicative, market-dependent — firm quote from GNEE sales, To be confirmed.
| 6061 T6 aluminum bar form | Indicative RMB/kg | Premium vs extruded base | Driver |
|---|---|---|---|
| Standard extruded round bar (Ø20–80 mm, ASTM B221) | 26.9 – 27.9 | 0% (base) | Single-pass extrusion, bulk supply |
| Large-diameter extruded bar (Ø80–180 mm) | 27.3 – 28.5 | +1 – 3% | Bigger section, slightly higher conversion |
| Extruded square / flat / hex bar | 27.5 – 29.0 | +2 – 5% | Non-round die complexity |
| Cold-drawn bright bar (h9/h11, ASTM B211) | 29.0 – 30.5 | +8 – 12% | Multi-pass drawing, tight tolerance, bright finish |
| Precision-ground bar (±0.02 mm) | 31.0 – 34.0 | +15 – 25% | Grinding passes, material loss, long lead |
| Clear anodized bar | 29.1 – 30.9 | +3 – 8% | Anodizing line + sealing |
| Forged 6061 T6 block / bar | 30.0 – 34.0 | +10 – 20% | Forging, low-volume tooling |
Five independent drivers stack on top of the base. Each is quantified so you can dial the spec to the budget.
| Driver | Effect on 6061 T6 aluminum bar price | Indicative magnitude |
|---|---|---|
| Temper (T6 vs T651) | T651 adds pre-stretch + stress-relief ageing | +3 – 6% |
| Surface (mill vs bright vs anodized) | Anodizing + sealing line, oxide-free bright finish | +3 – 8% |
| Tolerance (h11 vs h9 vs ground) | Tighter bands need more drawing/grinding passes | +8 – 25% |
| Certification (3.1 vs 3.2 / 3rd-party) | SGS / BV / TÜV witness and extra docs | +1 – 3% |
| Batch / MOQ | Small trial order vs full container or contract | +5 – 15% |
A premium only pays if the downstream saving or risk avoided exceeds it. Use these numerical triggers:
Where the spec is over-built, these substitutions recover cost with numbers, not adjectives:
| Move | Indicative saving | When it holds |
|---|---|---|
| Drop T651 → T6 | −3 – 6% | Parts not dimensionally critical after machining |
| Relax h9 → h11 (extruded) | −8 – 12% | Further machining removes the surface anyway |
| 6061 T6 → 6063 T5 (non-structural) | −5 – 10% | Decorative / light-duty, lower strength acceptable |
| Small trial → full container / contract | −5 – 15% | Demand is forecastable |
| Anodized → mill finish + post-paint | −3 – 8% | Paint system already specified downstream |
GNEE supplies 6061 T6 aluminum bar across the forms above. Typical range: diameter Ø6–300 mm (extruded), Ø4–100 mm (cold-drawn), length up to 6,000 mm cut-to-length, tempers T6 / T651, standards ASTM B221 / ASTM B211 / EN 754 / EN 755, with EN 10204 3.1 MTC as standard and 3.2 / third-party inspection on request. Full dimension and tolerance data is on the 6061 T6 aluminum bar specifications page.
Why is 6061 T6 aluminum bar priced above the SMM ingot price?The SMM A00 print is the raw ingot. Bar adds conversion — billet casting, extrusion or cold drawing, T6 heat treatment, straightening, cutting and inspection — which runs 3.4–7.0 RMB/kg depending on form and size, so the all-in bar price sits roughly 14–31% above the ingot. Conversion is a cost, not a market position, which is why it moves far more slowly than the ingot.
Which 6061 T6 aluminum bar form carries the highest premium?Precision-ground bar (±0.02 mm) carries the highest premium at +15–25% over the extruded base, followed by cold-drawn bright bar (h9/h11) at +8–12%. The premium is driven by extra drawing/grinding passes and tighter tolerances, not by alloy cost.
Is 6061 T6 aluminum bar subject to China export control?No. 6061 is a 6xxx alloy and is not on the dual-use control list, so it is exported as a standard commercial product. Export control applies only to certain high-strength 2xxx and 7xxx forms that meet defined strength and section thresholds.
What are the MOQ and lead time for 6061 T6 aluminum bar?MOQ is flexible — both small trial orders and large-volume, full-container or long-term contract orders are accepted, and larger orders are welcome. Typical lead time is 15–30 days from deposit, confirmed per size, temper and quantity.
