AA 5086 H24 Aluminum Alloy: Superior Strength, Corrosion Resistance, and Cost-Effective Performance
Aluminum AA 5086 is structural alloy, which offers users strong corrosion resistance and high electrical conductivity. Offering higher strength levels than 5052 or 5083, AA 5086 becomes stronger with stain hardening and cold working, all while remaining a cost-effective choice. It can be welded with conventional methods, though electric arc welding is preferred.
