Aluminum 5083 Plate applications
- Shipbuilding – hull plating, decks, bulkheads
- Offshore platforms – walkways, enclosures, load-bearing components
- Cryogenic tanks – LNG and low-temperature containers
- Chemical storage tanks – due to high corrosion resistance
- Military and naval crafts – patrol boats, armor plating
- Structural marine applications – ramps, superstructures, boat trailers
Quality & Certification
- ✅ ASTM B928, B209 compliance
- ✅ DNV, ABS, BV, RINA, CCS, and LR marine 3.2 certification (upon request)
- ✅ EN 10204 3.1 / 3.2 Mill Test Certificates
What is the difference between 5083 H116 and 5083 H321?
- H116: Strain-hardened and specially treated for marine applications, with superior corrosion resistance.
- H321: Also strain-hardened, but thermally stabilized for higher temperature service.
Both are marine-grade, but H116 is generally preferred for direct seawater exposure.
Is 5083 H116 aluminum plate weldable?
Yes. It is easily weldable using conventional methods like MIG and TIG welding. Post-weld strength and corrosion resistance remain excellent, which is why it’s preferred in marine fabrications.
What standards does 5083 H116 marine aluminum plate apply ?
5083 H116 is typically produced according to standards such as:
- ASTM B928/B928M (specifically for marine service)
- ASTM B209
- DNV, ABS, BV, LR certifications for shipbuilding
What thicknesses and sizes are available for 5083 H116 plates?
Common thicknesses range from 3mm to 100mm, with standard widths of 1000mm, 1220mm, 1500mm, 2000mm, and lengths up to 6000mm or custom-cut sizes.
