5083 Al-Mg-Mn Rust-Resistant Aluminum Alloy Rod

5083 is an Al-Mg-Mn series non-heat-treatable, corrosion-resistant aluminum alloy (designated as LF4 under the old Chinese national standard). Its strength is derived from solid-solution strengthening by magnesium; it cannot be strengthened through quenching and aging. It features excellent resistance to seawater corrosion, superior weldability, and outstanding low-temperature toughness. Common tempers include O (annealed/soft) and H112.

5083 is an Al-Mg-Mn series, non-heat-treatable, corrosion-resistant aluminum alloy (formerly designated as LF4 under the old Chinese national standard). Its strength is derived from solid-solution strengthening by magnesium; it cannot be strengthened through quenching and aging. It features excellent resistance to seawater corrosion, superior weldability, and outstanding low-temperature toughness. It offers fair machinability and good plasticity, though its appearance after anodizing is only average. Common tempers include O (annealed/soft) and H112; the density is 2.66 g/cm³.

Key comparison points: 5083 offers the best corrosion resistance (in seawater); as a non-heat-treatable alloy, its strength is lower than that of 6000-series or 7000-series alloys.

Mechanical properties

Tensile strength Rm	≥270 MPa
Yield strength Rp0.2	≥125 MPa
Post-fracture elongation A	≥12%
Brinell Hardness HB	≈70 HB

Note: O annealing soft state: Tensile strength ≥ 270 MPa, yield strength ≥ 110 MPa, elongation is higher and plasticity is better; The strength cannot be increased through heat treatment.

Application Scenarios

1. Marine and Offshore Engineering: Marine components, yacht structural parts, and offshore platform components; features resistance to seawater corrosion.

2. Cryogenic Equipment: LNG cryogenic storage tanks, liquid nitrogen/oxygen containers; exhibits excellent cryogenic toughness.

3. Pressure Vessels: Atmospheric liquid storage tanks and blanks for corrosion-resistant chemical vessels.

4. Transportation: Tanker bodies, dump truck beds, and welded components for rail transit.

5. Offshore Engineering: Coastal equipment, support structures in marine environments, and corrosion-resistant tooling.

6. General Welded Structures: Parts requiring welding and resistance to atmospheric or salt-spray corrosion.

Note: Cannot be strengthened by heat treatment; not suitable for ultra-high-load operating conditions; machining tends to produce long, continuous chips; decorative results from anodizing are generally mediocre.

Payment Methods

Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
