As an company with many years of experience in the aluminum processing industry, Haomei Aluminum understands the core value of 5000 series aluminum-magnesium alloys in corrosion resistance. 5086 H111 aluminum sheet, as a typical representative of rust-resistant aluminum, has become a preferred material in marine, transportation, and chemical industries due to its precise component ratio and stable processing technology.
In terms of core performance, 5086 H111 aluminum sheets, based on a scientifically designed Al-Mg alloy system, exhibit multi-dimensional advantages, specifically in three core dimensions:
- Corrosion resistance:
With magnesium content precisely controlled at 3.5%~4.5%, combined with 0.20%~0.7% manganese and 0.05%~0.25% chromium, a stable corrosion-resistant structure is formed. In harsh environments such as seawater and industrial atmospheres, its resistance to exfoliation corrosion and intergranular corrosion far surpasses that of ordinary aluminum materials, meeting the needs of highly corrosive scenarios such as marine and chemical industries.
- Mechanical properties:
Tensile strength ≥240MPa, yield strength ≥95MPa, elongation ≥12%, achieving a balance between rigidity and plasticity in medium-strength applications; furthermore, the H111 condition requires no special heat treatment and can be directly processed, effectively shortening customer production cycles and controlling costs.
- Processing performance:
Excellent weldability, perfectly compatible with conventional welding processes such as MIG and TIG, with minimal post-weld strength loss; it also possesses excellent cold-working forming capabilities, allowing for the manufacture of complex components through bending, stamping, and other processes, adapting to diverse production needs.
In the shipbuilding industry, 5086 aluminum sheet is an ideal material for yacht decks, side panels, and fuel systems. Its lightweight characteristics reduce hull energy consumption, and its corrosion resistance ensures a long service life for ships. Haomei Aluminum’s series of products has obtained certifications from several authoritative international classification societies, including the American Bureau of Shipping (ABS), Det Norske Veritas (DNV), Lloyd’s Register (LR), and the China Classification Society (CCS), and is being used in large quantities in shipbuilding projects in Brazil, Southeast Asia, and other regions. In the transportation and chemical industries, it can be used for refrigerated truck bodies, pressure vessel shells, and seawater storage tanks, with its low-temperature stability and fire resistance meeting international safety standards. Furthermore, in outdoor projects such as TV towers and exploration equipment, the weather resistance of this aluminum sheet can reduce the frequency of later maintenance and improve the overall project benefits.
Regarding specifications, Haomei 5086 H111 aluminum sheets offer a wide range of standard sizes and also support customized production to meet special needs: standard thicknesses range from 1.0 to 60 mm, widths from 500 to 2600 mm, and lengths from 500 to 13000 mm; wide, extra-long sheets, and special sizes can be customized according to customer project requirements to meet the installation and processing requirements of different scenarios.
Compared to the commonly used 5086 H116 aluminum sheet in the same series, the two have significantly different positioning, as detailed below:
| Comparison Dimensions | 5086 H111 Aluminum Sheet | 5086 H116 Aluminum Sheet |
| Core Performance | Medium strength, focusing on corrosion resistance and processability | High strength (tensile strength ≥305MPa), enhanced resistance to exfoliation corrosion |
| Applicable Scenarios | Conventional marine components, civil chemical equipment, outdoor engineering | Deep-sea vessels, high-pressure vessels, extreme corrosive environments |
| Processing Cost | No special heat treatment required, cost controllable | Requires special aging treatment, higher cost |
| Haomei Supply Advantages | Bulk stock, short lead time, supports customized processing | Customized production, with classification society certification. |
From a technical selection perspective, Haomei recommends: If customer needs focus on conventional corrosion resistance and processing efficiency, 5086 H111 aluminum sheet is a cost-effective choice; if extreme environments and high strength requirements are involved, 5086 H116 aluminum sheet can be selected. We can provide material alternatives and processing technology optimization suggestions based on the customer’s specific working conditions. Haomei 5086 H111 aluminum sheets ensure stable performance of each batch through strict component control and full-process quality inspection, helping global customers maximize project value.
