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

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

6061 aluminum flat slip-on flange with a flat sealing face ensures uniform gasket pressure, suitable for use with aluminum pipes or other lightweight piping, and is applied in marine piping systems.

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.
