5083 aluminum alloy is a commonly used aluminum-magnesium alloy with excellent corrosion resistance and high strength. Its different heat-treated tempers (e.g. H111, H116, H321) represent different mechanical properties and application characteristics. The following is a brief comparison of 5083 h111 vs h116 vs h321: 5083 H111 – Characteristics: 5083 aluminum alloy in H111 condition is simply annealed and has good …
