Marine Grade Aluminum | 5083 and 5086 aluminum plate difference

Aluminum sheet manufacturers introduce the requirements of Marine Grade Aluminum

Marine vessels are immersed in seawater for a long time. Due to the special environment, the requirements for the material of ship plates and sheet metal parts are very high. It is required to have excellent corrosion resistance, high strength, excellent welding performance and good molding properties. 5083 aluminum plate and 5086 aluminum plate can be used in the marine ship field, which has a good application effect.

5083 aluminum plate and 5086 aluminum plate have in common

Both the 5083 aluminum plate and the 5086 aluminum plate belong to the 5-series AL-Mg alloy and are widely used rust-proof aluminum. They are used in applications where high corrosion resistance, good weldability and moderate strength are required, such as ship, automotive and aircraft sheet weldables. And pressure vessels, refrigeration units, television towers, loading and unloading equipment, transportation equipment, etc., which require strict fire protection.

The difference between 5083 aluminum plate and 5086 aluminum plate

The main difference between the two grades of aluminum plates is the difference in chemical composition and mechanical properties.
5083 aluminum plate chemical composition content: Si: ≤ 0.4 Cu: ≤ 0.1 Mg: 4.0–4.9 Zn: 0.25 Mn: 0.40–1.0 Ti: ≤ 0.15 Cr: 0.05–0.25 Fe: 0.4
5086 aluminum plate chemical composition content: Mg: 3.5 ~ 4.5 Zn: ≤ 0.25 Mn: 0.20 ~ 0.7 Ti: ≤ 0.15 Cr: 0.05 ~ 0.25 Fe: 0.000 ~ 0.500
5083 Mechanical properties: Tensile strength σb (MPa): 110-136 Elongation δ10 (%): ≥20 Annealing temperature: 415 °C Yield strength σs (MPa) ≥110
5086 Mechanical properties: Tensile strength σb (MPa): ≥ 240 Conditional yield strength σ0.2 (MPa): ≥95 Elongation δ10 (%): ≥10 Elongation δ5 (%): ≥12
