What is 5086 H116 Aluminum?

5086 H116 aluminum refers to a 5086 aluminum alloy plate in the H116 temper, specifically engineered for excellent resistance to seawater corrosion and exfoliation corrosion.

The H116 temper is achieved through controlled cold working and stabilization processes, which ensure stable mechanical properties while significantly improving resistance to intergranular and marine corrosion.

• 5086: This represents the alloy series. The "5" indicates that this alloy series uses magnesium as the primary alloying element, giving it excellent corrosion resistance.
• H: Indicates the temper designation, which refers to a type of mechanical processing treatment.
• 116: Refers to a specific H temper, achieved through special surface treatment or processing to control and prevent exfoliation corrosion.
