Aluminum weld neck flanges are manufactured from aluminum alloys such as 5083, 6061, and 5086, offering lightweight characteristics, high strength, and excellent resistance to marine corrosion.

5083, 5086, and 6061 aluminum flanges feature lightweight construction, excellent thermal conductivity, and outstanding corrosion resistance, and are certified by major classification societies such as DNV-GL, ABS, LR, and CCS.

Marine aluminum flanges are made from 5xxx series (such as 5083 and 5086) or 6xxx series (such as 6061) aluminum alloys, and are connection components specifically designed for aluminum alloy piping systems used in ships and offshore engineering.
