5086 H111 Plate
5086-H111 Aluminum Plate is a marine-grade aluminum-magnesium alloy known for its outstanding corrosion resistance, moderate strength, and excellent weldability. It is widely used in maritime, transportation, and structural applications where durability in harsh environments is critical.
5086 is a non-heat-treatable aluminum-magnesium alloy from the 5xxx series, known for its excellent corrosion resistance, medium strength, and weldability. The H111 temper indicates that the alloy has undergone light strain hardening (rolling or cold working) followed by partial annealing to stabilize its properties, thus balancing formability and mechanical strength.
Haomei Aluminum specializes in the production of 5086 H111 medium-thick aluminum plates, with thickness ranging from 0.15-600mm to meet the demanding requirements of ships, automobiles, pressure vessels, and other harsh environments. We use advanced hot-rolling production lines, ensuring high precision (tolerance ≤±2mm), finely polished surfaces, strong seawater corrosion resistance, and support for custom cutting and welding services. We provide BV/DNV/ABS and other international certifications, with a quick response to custom needs.
5086 H111 Plate Alloy Composition
The main component of 5086 aluminum alloy is magnesium, which gives it high corrosion resistance, especially in seawater environments. The typical chemical composition includes:
- Magnesium (Mg): 3.5–4.5%
- Manganese (Mn): 0.2–0.7%
- Chromium (Cr): 0.05–0.25%
- Copper (Cu): ≤0.10%
- Iron (Fe): ≤0.5%
- Silicon (Si): ≤0.4%
- Titanium (Ti): ≤0.15%
- Zinc (Zn): ≤0.25%
- Others: each ≤0.05%, total ≤0.15%
- Balance: Aluminum (Al)
This composition ensures high strength and excellent corrosion resistance in marine environments.
5086 H111 Plate Mechanical Properties
The H111 temper indicates that the alloy has been strain-hardened, with a lower strength than the H32/H34 temper, achieving a balance between strength and ductility. Typical mechanical properties include:
- Tensile Strength: 260–300 MPa
- Yield Strength: 120–200 MPa
- Elongation: 12–20% (indicating good ductility)
- Hardness: approximately 60–75 Brinell Hardness (HB)
Note: The strength of H111 is lower than that of H32/H34, but its formability is better.
These properties make 5086-H111 aluminum suitable for applications that require moderate strength and good formability.
5086 H111 Plate Features
- Corrosion Resistance: Excellent performance in marine/coastal environments; resistant to seawater, chemicals, and industrial environments.
- Weldability: Easily welded using TIG, MIG, or resistance welding; good performance after welding.
- Formability: Due to the stable state of H111, it is suitable for bending, rolling, or forming.
- Non-heat-treatable: Strengthened only by strain hardening.
