5086 Aluminum Flat Bar Applications
5086 Aluminum Flat Bar in the Marine Industry
Core Structural Components in Shipbuilding
- Hull and Deck: 5086 aluminum flat bar is commonly used in hull outer plates, decks, sides, and bottom structures of ships. Its excellent seawater corrosion resistance effectively handles long-term immersion in marine environments, reducing maintenance costs, while its moderate strength ensures the stability of the hull structure.
- Engine Mounts and Welded Components: Its good weldability makes it suitable for welded structural components such as engine mounts and bulkhead connectors, ensuring structural integrity and airtightness.
Marine Engineering Equipment and Storage & Transport Equipment
- LNG Tanks and Cryogenic Containers: 5086 aluminum alloy maintains excellent mechanical properties in low-temperature environments, making it suitable for manufacturing liquefied natural gas (LNG) tanks, refrigerated containers, and cryogenic liquid transport tanks, meeting strict explosion-proof and low-temperature requirements.
- Offshore Platforms and Drilling Equipment: 5086 aluminum flat bar is used in offshore oil and gas platforms, drilling equipment to support structures and protective housings, with its salt spray corrosion resistance extending the equipment's service life.
Ship Protection and Special Purposes
- Armor Plates and Bulletproof Structures: 5086’s high strength and impact resistance make it ideal for armor protection plates on naval vessels, especially in military ships that require both lightweight and corrosion resistance.
- Anti-slip Decks and Fittings: By surface treatment (e.g., patterned rolling), 5086 aluminum flat bar can be made into anti-slip decks, widely used in yachts, ferries, and other ships to enhance safety.
Supporting Equipment and Auxiliary Systems
- Pipelines and Pressure Vessels: Used in ship fuel pipelines, seawater cooling systems, and non-combustible pressure vessels, its corrosion resistance reduces the risk of leaks due to media erosion.
- Electrical Equipment Housings: In ship distribution cabinets, high-voltage switchgear housings, etc., 5086’s corrosion resistance protects internal components from the impact of the marine humid environment.
Here’s the technical advantage and application scenario for 5086 aluminum flat bars in a table format:
| Technical Advantage | Details |
| Corrosion Resistance | 5086 Aluminum contains 3.5%-4.5% Magnesium, along with trace amounts of Manganese and Chromium, forming a dense oxide layer. This significantly enhances its resistance to seawater and salt spray corrosion, especially in long-term immersion environments. |
| Welding and Machining Performance | Excellent cold working performance, can be formed at room temperature without preheating. High welding compatibility (e.g., gas welding, arc welding), and welds have high strength, making it suitable for complex hull structure manufacturing. |
| Lightweight and Strength Balance | Low density (about 2.7 g/cm³), with a tensile strength of over 240 MPa. This allows it to reduce the weight of the hull while maintaining structural strength, in line with the trend toward lightweight shipbuilding. |
| Certifications and Standardization | Certified by classification societies (e.g., CCS, DNV), and compliant with international standards like ASTM and EN, ensuring material reliability in marine environments. |
What Other Fields is 5086 Aluminum Flat Bar Used In?
- Military: Vehicle armor.
- Industrial: Pressure vessels, cryogenic equipment, oil and gas pipelines, and structural supports.
