Types of Marine Grade Aluminum Alloys

Aluminum alloys are generally classified according to the primary alloying element added to aluminum and the alloys' ability to respond to thermal and mechanical treatment. Cast aluminum alloys are formed by pouring molten liquid metal into molds of requisite shapes and cooled; solid metal is mechanically deformed or forged or rolled to the required shape to form wrought aluminum alloys.
Marine grade wrought aluminum alloys usually comprise aluminum-magnesium (Al-Mg) alloys and aluminum-magnesium-silicon (Al-Mg-Si) alloys. They are generally used in structural shipbuilding, boat lifts, docks, and other offshore structural applications.
Cast aluminum alloys are used in numerous marine applications because casting processes can create relatively complex shapes, including ships' superstructures, structural components, interior fixtures and various supports. They are usually aluminum-silicon (Al-Si) or Al-Mg alloys.
