❓ Frequently Asked Questions
What is 5083 aluminum coil?
5083 aluminum coil is a high-strength 5000 series aluminum-magnesium alloy product. It is the strongest commonly available non-heat-treatable aluminum alloy, known for exceptional marine corrosion resistance, outstanding cryogenic performance, and excellent weldability. It is widely used in shipbuilding, offshore structures, LNG tanks, and pressure vessels.
What is the difference between 5083 and 5052 aluminum coil?
5083 has a significantly higher magnesium content (4.0–4.9% vs 2.2–2.8%) than 5052, which results in substantially higher strength and better corrosion resistance, particularly in severe marine and offshore environments. 5083 is also the preferred alloy for cryogenic applications. 5052 is more suitable for general-purpose marine and industrial forming applications where the extreme performance of 5083 is not required.
What tempers are available for 5083 aluminum coil?
Common tempers include O, H111, H116, and H321. O and H111 tempers are softer and more suitable for forming and bending operations. H116 and H321 are the standard marine tempers that provide higher strength and are specifically designed to resist sensitization and stress corrosion cracking in seawater environments.
Why is 5083 aluminum used for LNG storage tanks?
5083 aluminum retains excellent mechanical toughness and ductility at cryogenic temperatures as low as -196°C, unlike many other structural materials that become brittle at low temperatures. Its combination of high strength, weldability, and cryogenic toughness makes it the standard material for LNG storage and transport vessels.
Is 5083 aluminum coil certified by classification societies?
Yes. 5083 aluminum is approved and certified by major international marine classification societies including ABS, DNV GL, Lloyd's Register (LR), Bureau Veritas (BV), NK, and RINA. We can provide coils with the relevant classification society certificates for approved shipbuilding and offshore projects.
What is the difference between H116 and H321 temper for 5083?
Both H116 and H321 are marine tempers for 5083 with similar mechanical properties. H116 is achieved through controlled cold working while H321 involves a low-temperature thermal stabilization process. Both tempers are designed to provide equivalent resistance to exfoliation corrosion and stress corrosion cracking in seawater, and both are accepted by marine classification societies for shipbuilding applications.
