GB 5A06 H112 Aluminum Plate Description
Among the 5000-series aluminum alloys, 5A06 contains one of the highest levels of magnesium (up to 6.8%). This specific chemical composition provides exceptional load-bearing capabilities.
The 5A06 H112 temper indicates that the plate is manufactured with some strain hardening during the shaping process (usually hot rolling) without special control over the thermal treatment. This results in stable, reliable mechanical properties, ensuring the plate will not deform unpredictably during your subsequent machining or welding processes.

When buying thick aluminum plates (especially those over 20mm), internal defects like porosity, cracks, or inclusions are a major concern. GNEE conducts rigorous Ultrasonic Testing (UT) on our heavy plates. This non-destructive testing ensures the internal structure is completely sound, preventing failures during deep processing or heavy-load operations.
Require full material traceability?
We provide an EN 10204 3.1 Mill Test Certificate (MTC) with every shipment. Contact us to see a sample MTC and learn more about our strict ultrasonic testing procedures for heavy plates.
Fabrication and Processing Performance of 5A06 H112 aluminum plate
Understanding how 5A06 H112 behaves in a factory setting is critical for production planning.
- Weldability: Outstanding. This is one of the main reasons engineers choose 5A06. It can be reliably welded using TIG or MIG processes without suffering from hot cracking. The strength of the welded joint can reach over 90% of the base metal. ER5183 or ER5356 welding wire is highly recommended.
- Machinability: Fair to good. Because it is a non-heat-treatable alloy, it is softer than the 7000-series. Machinists should use sharp, high-speed steel or carbide tools with generous rake angles and ample lubrication/coolant to avoid chip buildup on the cutting edge.
- Formability: Moderate. Due to its high strength, 5A06 is relatively stiff. It is not suitable for complex deep drawing or tight-radius bending. It is primarily designed for flat structural applications or large-radius rolling.
Core Applications of GB/T 5A06 H112 Aluminum Plate
The combination of high tensile strength, resistance to saltwater, and excellent weldability makes 5A06 the material of choice for demanding industrial sectors.
Shipbuilding and Marine Structures:
Used for hull construction, main decks, superstructures, and offshore platform components. It resists marine atmospheric corrosion, drastically reducing maintenance costs over the vessel's lifespan.
Heavy-Duty Pressure Vessels:
Because it retains high strength at welded seams, it is heavily used to manufacture industrial storage tanks, chemical pipelines, and gas cylinders.
Cryogenic and Low-Temperature Applications:
Unlike steel, aluminum does not become brittle at freezing temperatures. 5A06 maintains its toughness at cryogenic temperatures, making it ideal for Liquefied Natural Gas (LNG) storage and transport equipment.
Transportation Equipment:
Applied in the manufacturing of railway cars, heavy dump trucks, and fuel tankers. It reduces the vehicle's dead weight, thereby increasing payload capacity and saving fuel.
Welded Structural Components:
Used in military armor, bridge components, and heavy machinery bases where structural integrity cannot be compromised.
5A06 vs 5083 Aluminum
For international buyers, the most common question is how 5A06 compares to the universally known 5083 marine-grade aluminum.
Compared to 5083 aluminum, 5A06 contains higher magnesium content (up to 6.8% vs. 4.9%), offering higher tensile strength, while maintaining similar excellent corrosion resistance and weldability.
If your project specifies the Chinese GB/T standard and requires maximum strength from a non-heat-treatable alloy, 5A06 is the superior choice. If you require materials with specific international marine classifications (like DNV or ABS), 5083 is the more standard commercial option. GNEE supplies both.
