5083 H321 aluminum is a high-strength alloy known for its excellent corrosion resistance, especially in marine environments. It has a significant magnesium content, contributing to its durability and toughness. This alloy doesn't require heat treatment, yet it offers outstanding mechanical properties. Its combination of strength, corrosion resistance, and formability makes it ideal for industries that require reliable and durable materials.
The 5083-H321 aluminum plate is recognized for its outstanding performance in extreme environments, particularly in marine and industrial applications. As part of the 5xxx aluminum-magnesium alloy series, it is an ideal rust-resistant material with exceptional corrosion resistance, excellent weldability, and good cold workability. Known for its resistance to seawater and harsh chemicals, the most common temper of 5083 is H321.
This alloy maintains excellent strength even after welding, offering the highest strength among non-heat-treatable alloys. However, it is not recommended for use at temperatures above 65°C. With a magnesium content exceeding 4.0%, it also provides good mechanical properties and resistance to exfoliation corrosion. The tensile strength of 5083-H321 is greater than 305 MPa, with a yield strength greater than 215 MPa, elongation exceeding 20%, and 5% elongation above 12%.
Applications for 5083-H321 aluminum plates are extensive, including use in marine superstructures, storage tanks, ferries, yachts, patrol boats, drilling platforms, and parts like engine bases, ship sides, and bottom plates.
Comparing 5083-H321 to other alloys:
5086 alloy, a premium choice for marine environments, is stronger than 5083. Though they have similar properties, 5086 is more robust, especially when cold-worked.
6061 aluminum alloy, while heat-treated to achieve medium strength, offers higher strength than 5083. It also has better machinability than 5083-H116.
