Yes, aluminum 5086 forged fittings are highly corrosion resistant. This alloy is known for its exceptional resistance to both seawater and industrial chemical environments, making it an ideal choice for marine and industrial piping applications.

The corrosion resistance of 5086 aluminum forged fittings is due to its composition, which includes high levels of manganese, chromium, and zinc. These elements form a protective oxide layer on the surface of the fittings that prevent the ingress of corrosive agents. In addition, the forging process of these fittings improves the resistance to stress corrosion cracking, as well as pitting corrosion, when compared to other forms of 5086 alloy.

It is worth mentioning that the surface finish and proper maintenance play an important role in the corrosion resistance performance of aluminium 5086 forged fittings. Any damage or surface alteration will compromise the barrier effect of the protective oxide layer, so surface treatment such as anodizing, painting and proper cleaning are crucial to maintain its corrosion resistance over time.
