5083 Aluminum Square Tube
5083 Aluminum Square Tube suppliers offer standard cross-sections of 10-220mm × 10-220mm, wall thicknesses of 0.8-25mm, and standard lengths of 3-6m, with custom cutting available upon request. Common tempers are O/H111/H112/H32/H34, and non-standard/large-diameter customization is supported, suitable for high-strength corrosion-resistant applications such as marine engineering, shipbuilding, and pressure vessels.
5083 Aluminum Square Tube is an Al-Mg series non-heat-treatable, rust-resistant aluminum alloy. Its core advantages are high corrosion resistance, excellent weldability, and moderate strength. With a density of approximately 2.66 g/cm³, it exhibits excellent low-temperature performance, making it a preferred material for marine and outdoor engineering.

Manufacturer Selection Recommendations
1. Outdoor scenarios requiring resistance to seawater/salt spray and welding (e.g., offshore platforms, ships) → 5083 is the first choice.
2. Low-temperature environments and pressure vessels (e.g., liquid nitrogen storage tanks, refrigerated trucks) → 5083 performs excellently.
3. For those seeking ultimate machinability → Consider 6061 (heat-treated for enhanced strength, smoother machining).
4. For those requiring higher strength → Consider 7075 (but with poor weldability and weak corrosion resistance).
