5A06-H112 Aluminum Plate Description
5A06-H112 aluminum plate is a high-magnesium, non-heat-treatable aluminum alloy known for its excellent corrosion resistance, high weldability, and medium-to-high strength. Among the 5000-series aluminum alloys, 5A06 contains one of the highest levels of magnesium (up to 6.8%), which gives it superior resistance to marine and industrial atmospheres.
5A06-H112 aluminum alloy plate is widely used in marine structures, shipbuilding, pressure vessels, and transportation equipment where long-term durability, fatigue strength, and lightweight performance are strictly required.
The H112 temper means that the aluminum plate has been strengthened by being shaped (like through hot or cold rolling) without any specific control over how much it was strengthened or heated. This temper guarantees stable mechanical properties and structural integrity, making it ideal for immediate industrial machining and welding.
As a direct manufacturer and supplier, GNEE China offers 5A06-H112 aluminum plates with accurate thickness measurements, various alloy options, and completely customized sizes to fit different heavy industry requirements around the world.

5A06-H112 Aluminum Machining and Processing Performance
Understanding how 5A06-H112 behaves during manufacturing is critical for your production line.
- Weldability (Excellent): This is a standout feature of 5A06. It performs exceptionally well with standard welding methods like TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. The weld seam retains high strength and does not easily crack. ER5183 welding wire is typically recommended.
- Corrosion Resistance (Excellent): The alloy naturally forms a dense oxide layer. It is highly resistant to seawater, industrial chemicals, and atmospheric corrosion, eliminating the need for frequent painting or maintenance.
- Formability (Good): In the H112 temper, it retains enough ductility for standard bending and forming, though it is stiffer than lower-magnesium alloys like 5052.
- Machinability (Fair to Good): Because it is a non-heat-treatable, relatively soft alloy compared to the 7000 series, high-speed steel or carbide tools with generous rake angles and plenty of coolant are recommended to avoid continuous chip buildup.
Core Applications of 5A06-H112 Aluminum Plate
Due to its specific blend of low weight, high structural strength, and rust resistance, 5A06 is the material of choice for demanding environments.
- Shipbuilding and Marine Engineering:
Used extensively for boat hulls, decks, superstructures, and offshore oil rig components. It can withstand constant exposure to saltwater without degrading.
- Pressure Vessels and Storage Tanks:
Its excellent weldability and strength make it perfect for manufacturing welded pressure vessels, chemical storage tanks, and pipelines.
- LNG (Liquefied Natural Gas) Equipment:
5A06 maintains its toughness and does not become brittle at extremely low cryogenic temperatures, making it suitable for LNG storage and transport.
- Transportation Equipment:
Used in railway tankers, truck trailers, and coal carriages. The lightweight nature of the aluminum plate increases vehicle payload capacity while reducing fuel consumption.
- Heavy Duty Welded Structures:
Applied in military equipment, armor plates, and structural components requiring a high strength-to-weight ratio.

Alloy Comparison: 5A06 vs. 5083 vs. 5052
To make an informed purchasing decision, it helps to understand how 5A06 compares to other common marine-grade aluminum plates.
Compared with 5083 aluminum, 5A06 offers a higher magnesium content (up to 6.8% vs. 4.9% in 5083). Because of this difference, 5A06 provides slightly higher tensile strength and fatigue resistance. While 5083 is the most common standard marine grade globally, 5A06 is often selected for more demanding structural applications where extra load-bearing capacity is required while maintaining the same excellent corrosion resistance.
Compared with 5052 aluminum, 5A06 is significantly stronger. 5052 has a lower magnesium content (around 2.5%), making it softer, easier to bend, and highly formable. 5052 is usually used for sheet metal parts, fuel tanks, and cabinets. If your project requires rigid structural support or heavy welding (like a ship hull), 5A06 is the far superior choice.
