Aluminium alloy 5083 contains 5.2% magnesium, 0.1% manganese and 0.1% chromium. In the tempered condition, it is strong, and retains good formability due to excellent ductility. 5083 has high resistance to corrosion, and is used in marine applications. It has the low density and excellent thermal conductivity common to all aluminium alloys.
Typical Applications require a weldable alloy of high to moderate strength, with good corrosion resistance. Marine applications, unfired welded pressure vessels, TV towers, drilling rigs, transportation equipment, armour plate.
Description Aluminium 5083 is a strong magnesium-manganese-chromium-aluminium alloy. It can be hardened by cold work, but is not heat treatable to higher strength. It has good ductility for the strength level, better than most other 5000 series alloys (see figure).
Corrosion Resistance Alloy 5083 has excellent resistance to general corrosion, and is used in marine applications. Resistance is excellent in aqueous solutions in the pH range 4 – 9. The corrosion resistance of aluminium alloys relies on a protective surface oxide film, which when damaged is readily repaired by the rapid reaction between aluminium and oxygen. However, the high reactivity of the base metal can give rapid corrosion if the film cannot be repaired, so aluminium alloys are not suitable for use with reducing media. Alloy 5083 can be anodised to improve the corrosion resistance by thickening the protective surface film.
Alloy 5083 can be susceptible to exfoliation corrosion in severe applications. Material in the H116 temper is least susceptible, and passes the ASTM G66 Exfoliation Susceptibility Test (ASSET Test). AS 1734 suggests alloy 5083 should not be used above 65°C.
Pressure Vessels AS1210 Pressure Vessels prequalifies alloy 5083 for pressure service for temperatures up to 65°C in the O, H112 & H321 tempers.
