Tra 5052 mae alwminiwm yn aloi alwminiwm amlbwrpas a ddefnyddir yn gyffredin sy'n addas ar gyfer llawer o gymwysiadau, nid yw'n cael ei ddefnyddio fel arfer mewn adeiladu llongau, yn enwedig ar gyfer cydrannau strwythurol hanfodol. Mae'r diwydiant adeiladu llongau yn aml yn gofyn am ddeunyddiau sy'n bodloni manylebau llym ar gyfer cryfder, gwydnwch a gwrthsefyll cyrydiad, ac nid dyma brif briodweddau 5052 alwminiwm.

5052 aluminum alloy is known for its high strength, good corrosion resistance and excellent weldability. It is commonly used in applications such as ships and marine components, as well as other non-structural components where weight and corrosion resistance are important, such as fuel tanks, hulls and various marine equipment.

Fodd bynnag, for the shipbuilding industry, especially in areas where structural integrity and high-strength materials are required, more specialized aluminum alloys or steels are preferred. Common marine grade aluminum alloys used in shipbuilding applications include:

5083 Alwminiwm: This alloy has excellent strength, ymwrthedd cyrydiad, and weldability, making it ideal for shipbuilding. It is commonly used in the construction of ship hulls and superstructures.

5086 Alwminiwm: Tebyg i 5083, 5086 aluminum has good strength and corrosion resistance and is used in a variety of marine applications.

6061 Alwminiwm: While not as corrosion-resistant as 5083 a 5086, 6061 aluminum is known for its high strength and is sometimes used in certain shipbuilding components.
