概述
5086-H116 is a non-heat-treatable Al-Mg (5000-series) aluminum alloy sheet and plate product. The H116 temper is a specialized marine-grade temper — controlled straining after final annealing — specifically designed to provide excellent resistance to intergranular corrosion and exfoliation corrosion while maintaining good strength. This combination makes 5086-H116 one of the most widely used aluminum alloys for marine and saltwater-exposed structural applications.
