5083 aluminum pipe for Marine & Pressure Applications

What is 5083 aluminum tube?

5083 aluminum tube is a high-magnesium aluminum alloy product that belongs to the Al-Mg series. As a non-heat-treatable alloy, 5083 delivers outstanding strength through cold working rather than thermal processing. Its chemical composition includes 4.00–4.90% magnesium as the primary alloying element, which gives it excellent corrosion resistance—especially in marine environments—and superb weldability.This alloy performs differently depending on its temper. In a semi-cold-worked (H116/H321) condition, it maintains good formability and plasticity. However, in fully cold-worked states, its ductility may decrease while strength increases.5083 aluminum tubing offers high strength, corrosion resistance, and ease of welding, making it ideal for structural applications requiring durability and reliability in harsh conditions. Common applicable standards for 5083 aluminum tube include ASME B36.10M / B36.19M in the United States and EN AW‑AlMg4.5Mn0.7 (corresponding to EN 573 and EN 755 series) in Europe. To view applicable standards, please refer to the specific 5083 aluminum tube standard table.
