Recently, GNEE successfully produced and exported a batch of 6061-T6 aluminum round bars to Thailand. This shipment was specifically manufactured to meet marine and heavy industrial application standards. The entire batch is fully certified by BV (Bureau Veritas), conforming strictly to marine-grade requirements.
We provided full inspection reports, strict dimensional control, and export-grade packaging to ensure the material performs reliably in demanding tropical environments.

Test Results
This order strictly follows the BV Rules for Materials and Welding for Marine Units. As a professional purchaser knows, having material that simply meets the minimum standard is not enough. You need a safe margin to ensure stable machining. Before shipping, we tested the mechanical properties of these bars.
- Tensile Strength: Standard requirement is ≥260 MPa. Our actual test result is 311 MPa.
- Yield Strength: Standard requirement is ≥240 MPa. Our actual test result is 287 MPa.
- Elongation: Standard requirement is ≥8%. Our actual test result is 18.0%.
The actual test results fully exceed the standard requirements. For end-users, an elongation of 18.0% in a T6 temper is an excellent indicator. It means the aluminum bar maintains high strength without becoming brittle. When your CNC machines are milling or turning these thick 260mm bars, the material will chip predictably and resist cracking under stress.
Chemical Composition (Actual Tested Values)
| Element | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti |
|---|---|---|---|---|---|---|---|---|
| Content (%) | 0.6004 | 0.1251 | 0.1688 | 0.0956 | 0.9239 | 0.2224 | 0.0177 | 0.0493 |
This specific balance of Magnesium and Silicon forms the Mg2Si compound, which gives the 6061-T6 alloy its core structural strength. The controlled addition of Copper (0.1688%) ensures good machinability, while Chromium (0.2224%) helps improve the overall corrosion resistance, which is critical for marine applications in Thailand.
Quality Control
When buying thick aluminum bars like Ø260 mm, buyers often worry about internal defects. A solid core is mandatory. During our final inspection, we performed macrostructure checks and surface inspections.
The inspection confirmed:
- No shrinkage defects
- No internal inclusions
- No cracks
- No material layering
- No overheating during the heat treatment process
This level of quality control fully complies with marine-grade inspection rules. Every shipment from GNEE includes an EN 10204 3.1 Mill Test Certificate and a full factory inspection report. We also fully support third-party inspections like SGS or BV based on customer requests.
Tolerance Control
Precision tolerance directly impacts your production costs. If an aluminum bar is out of round or oversized, you waste expensive machine time fixing it. GNEE ensures strict dimensional accuracy on all large round bars.
For this order, our tolerance control was:
- Diameter Range (Ø200–300 mm): Controlled within ±0.20 to 0.50 mm.
- Length (3000 mm): Controlled within ±1 mm.
To achieve this, we use precise saw cutting equipment with stable feed rates. We also conduct straightness inspections and roundness control before packing. Good roundness means less time spent truing the material on your lathe.
Tight tolerances mean lower machining costs and less material waste for your factory. If you need custom diameter and length cutting for 6061, 5083, or 6082 aluminum bars, contact our sales team now to get exact pricing.
Common Uses of 6061-T6 Aluminum Round Bars
Why is 6061-T6 popular in Thailand? Thailand has a strong manufacturing sector focusing on marine equipment, machinery production, and mold manufacturing. 6061-T6 provides an ideal balance of structural strength, corrosion resistance, and processing performance.
Common practical applications for these Ø260 mm solid bars include:
- Marine Parts: Deck fittings, custom mounting brackets, and heavy-duty structural connectors that require salt-water resistance.
- Machinery Components: Support columns, heavy guide rollers, custom gears, and transmission shafts used in factory automation.
- Mold Manufacturing: Standard tooling plates, blow molding cavities, and low-pressure injection molds for plastic manufacturing.
Packaging Methods
Sea freight introduces salt air and high humidity, which can easily cause white oxidation spots (water stains) on bare aluminum.
To adapt to Thailand's tropical climate and the sea journey, GNEE uses a strict export packaging process:
- Anti-Rust Oil Coating: A light layer of protection is applied to block moisture from touching the metal surface.
- Waterproof Plastic Film: We wrap the bars tightly in plastic to seal out humid air.
- End Protection: Hard caps are placed on the ends of the bars so the strict ±1 mm length tolerance is not ruined by forklift bumps during loading.
- Wooden Case & Steel Frame: The heavy bars are safely secured in sturdy wooden cases or steel frames to prevent any transport deformation.
