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

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.

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

Using 6061-T6 aluminum flanges can significantly reduce the weight of the exhaust system and even the entire ship, which has a direct benefit on increasing the ship's load capacity and reducing fuel consumption.

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