Aluminum Flange IntroductionAn aluminum flange is a pipe fitting made of aluminum, commonly used at the end of pipelines to connect with valves, pumps, instruments, or other equipment.

Aluminum flanges are made from aluminum alloys such as 5052, 5083, or 6061, and are manufactured through machining or casting processes.

The lightweight design, fatigue resistance, and easy machinability of 5083 and 6061 aluminum flanges make them widely used in modern shipbuilding.

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.

Marine-grade aluminum alloy flange fittings refer to flanges and related connectors made from specialized marine aluminum materials such as 5083, 5052, and 6061.

As a core component of marine piping systems that bears pressure, connects, and seals, flange joints are made of 5086 marine aluminum alloy.
