5083-H116 aluminum refers to 5083 aluminum in the H116 condition. Achieving this state requires treating the metal in a specific way to produce a particular level of intergranular corrosion and exfoliation corrosion resistance.
5083 H116 aluminum denotes 5083 aluminum alloy in the H116 condition. The H116 state is achieved through specific heat treatment and processing to enhance the alloy's resistance to intergranular and exfoliation corrosion. This process ensures that the material exhibits excellent strength and durability while maintaining a high level of corrosion resistance, especially in harsh marine environments.
5083 H116 condition is particularly suited for applications where aluminum will be exposed to severe conditions, such as marine structures and pressure vessels, where long-term performance and corrosion resistance are crucial.
5083 H116 is an aluminum alloy that, after special heat treatment, enhances its resistance to intergranular and exfoliation corrosion.
