5083 Anti-rust Aluminum Alloy

5083 refers to a 5-series high-magnesium, corrosion-resistant aluminum alloy (EN AW-5083, AlMg4.5Mn0.7). It cannot be strengthened by heat treatment and contains 4.0%–4.9% magnesium, with additions of manganese and chromium. It offers higher strength than 5052 or 5754 alloys, exhibits excellent resistance to seawater and salt-spray corrosion, possesses outstanding low-temperature toughness, and experiences minimal loss of strength after welding.

5083 is 5xxx high Mg anti-corrosion aluminum alloy (EN AW-5083, AlMg4.5Mn0.7), non-heat-treatable. Mg 4.0~4.9% with Mn & Cr. Higher strength than 5052 & 5754. Outstanding seawater corrosion resistance and low-temperature toughness, minor strength loss after welding. Common tempers: O, H112, H116, H321. H116/H321 marine grade with excellent exfoliation corrosion resistance. Widely used for shipbuilding, offshore engineering, LNG tanks, tankers. Available with CCS/DNV/ABS marine certificates, top choice for marine export projects.

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.
