When sourcing industrial materials globally, matching regional aluminum grades to international standards is a common challenge for procurement managers and engineers. If your blueprints specify 5A06 aluminium, understanding its international equivalents is crucial for securing the right material.
5A06 aluminium is a high-magnesium, non-heat-treatable Al-Mg alloy defined under the Chinese GB/T standard. It is generally equivalent to AlMg6 in ISO standards and AMG6 in the Russian GOST standard, sharing a similar chemical composition, high strength, and excellent corrosion resistance.
This comprehensive guide breaks down the precise international equivalents of 5A06, details its technical properties, and explains why it is a preferred material for heavy-duty marine and aerospace applications.
International Equivalent Grades of 5A06 Aluminium
Because aluminum alloys are standardized differently across the globe, a direct 1:1 match isn't always available, but highly equivalent grades exist based on chemical composition and mechanical performance.
Below is the definitive cross-reference guide for 5A06 aluminium:
| Standard System | Governing Body / Region | Equivalent Grade |
| China (GB/T) | Standardization Administration of China | 5A06 |
| ISO | International Organization for Standardization | AlMg6 |
| Russia (GOST) | Euro-Asian Council for Standardization | AMG6 (АМг6) |
| USA (UNS) | Unified Numbering System | A95006 (Approximate) |
| Europe (EN) | European Norms | EN AW-5A06 (Limited commercial use) |
Understanding the Equivalency:
The equivalence between GB/T 5A06, ISO AlMg6, and GOST AMG6 is widely accepted in international manufacturing. They share the same core metallurgical philosophy: using a very high magnesium content (around 6%) to achieve maximum strength in a non-heat-treatable alloy, without compromising weldability.
You do not need to search for local suppliers. GNEE manufactures 5A06/AlMg6 strictly according to international chemical compositions. Please provide us with your required specifications, and we will promptly offer a precise CIF/FOB quote.
5A06 Aluminium Chemical Composition
To prove the equivalency of these grades, we must look at their chemical makeup. The performance of 5A06 (and its equivalents) is driven by its high magnesium content.
| Element | Minimum Content (%) | Maximum Content (%) |
| Magnesium (Mg) | 5.8 | 6.8 |
| Manganese (Mn) | 0.5 | 0.8 |
| Silicon (Si) | - | ≤ 0.40 |
| Iron (Fe) | - | ≤ 0.40 |
| Copper (Cu) | - | ≤ 0.10 |
| Zinc (Zn) | - | ≤ 0.20 |
| Titanium (Ti) | 0.02 | 0.10 |
| Aluminum (Al) | Remainder | Remainder |
Why This Matters:
High Magnesium (5.8 - 6.8%): 5A06 has one of the highest magnesium levels in the 5xxx series. This makes the alloy exceptionally strong without the need for thermal treatment.
Manganese Addition (0.5 - 0.8%): Manganese works with magnesium to refine the grain structure, further enhancing the tensile strength and improving the metal's resistance to impact and fatigue.
Key Properties of 5A06 (AlMg6 / AMG6) Aluminium
When you source 5A06 or its equivalents, you are investing in a specific set of high-performance physical and mechanical traits.
Mechanical & Performance Features
| Property Category | Technical Description |
| Strength | High strength among 5xxx alloys. Due to the ~6% Mg content, it outperforms common grades like 5052 and even 5083 in sheer tensile capacity. |
| Tensile Strength (H112 temper) | 290 – 360 MPa. This guarantees structural integrity under heavy static or dynamic loads. |
| Yield Strength (H112 temper) | ≥ 145 MPa. Ensures the metal resists permanent deformation when subjected to stress. |
| Corrosion Resistance | Excellent resistance to seawater and marine atmosphere. The alloy naturally forms a robust, passive oxide layer that prevents rust and degradation, even when submerged in saltwater. |
| Weldability | Excellent. It can be easily welded using TIG or MIG processes. The joint strength can reach up to 90–95% of the base metal's strength, making it ideal for large welded assemblies. (ER5183 or ER5356 filler wire is recommended). |
| Low-Temperature Behavior | Maintains toughness at -40°C and below. Unlike carbon steel, which becomes brittle in the cold, 5A06 retains its ductility at cryogenic temperatures. |
| Machinability | Fair to Good. Because it is not a hard, heat-treatable alloy (like 7075), care must be taken during machining to prevent continuous chips. High speeds and proper coolant are advised. |

Main Applications of 5A06 Aluminium
Due to its highly balanced performance of strength, rust resistance, and weldability, 5A06 (AlMg6) is categorized as a heavy-duty industrial material. It is rarely used for simple sheet metal work, but rather for critical structural applications:
- Marine Engineering & Shipbuilding:
Used extensively for ship hulls, main decks, offshore oil platforms, and hovercraft structures. Its ability to withstand continuous exposure to saltwater while supporting massive weights is unmatched.
- Pressure Vessels & Storage Tanks:
Its excellent weldability means it can be fabricated into high-pressure gas containers, chemical storage tanks, and industrial pipelines without the risk of weld-zone failures.
- Aerospace & Defense:
While the 7000-series is common in aerospace, 5A06 is frequently used for welded missile components, military aircraft fuel tanks, and armor plating for light-armored vehicles where high impact resistance is required.
- Cryogenic Equipment:
Because it does not become brittle at extreme freezing temperatures, 5A06 is an excellent choice for manufacturing LNG (Liquefied Natural Gas) transportation tankers and cryogenic storage facilities.
5A06 vs. 5083 Aluminium in Global Trade
Although 5A06 is metallurgically equivalent to AlMg6 and AMG6, it is most often compared to 5083 aluminum in daily international trade.
If a buyer cannot source 5A06 locally, 5083 is the most common commercial alternative. Here is what you need to know about comparing them:
- Similarities: Both are 5000-series marine-grade alloys, both offer exceptional weldability, and both are used in shipbuilding and pressure vessels.
- The Difference: 5A06 contains slightly higher magnesium (up to 6.8%) compared to 5083 (up to 4.9%). Therefore, 5A06 offers slightly higher tensile strength.
- Standardization: 5083 is more universally recognized across ASTM (USA) and EN (Europe) standards, and holds more global marine certifications (DNV, ABS). 5A06 (or AlMg6) is preferred in projects utilizing Russian (GOST) or Chinese (GB) engineering standards requiring maximum non-heat-treatable strength.
In short: If you strictly need the highest strength, stick with 5A06. If you need a widely certified, internationally ubiquitous marine plate, 5083 is an acceptable substitute in many cases.
