Marine aluminum plate

 Aluminum specializes in marine grade alloys. Whether you are building Fast Ferries, Navy or passenger ships, yachts, or small pleasure craft we maintain a large inventory of sheets, plates and extrusions in 5083, 5086, 5454, 5052 and 5456 alloys to meet your needs.


5083 Aluminum Alloy plate– 5083 aluminum plates to satisfy the requirements for many industries. 5083 aluminum plate has higher strength than 5052 plate and a high resistance to corrosion. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine applications.
5086 Aluminum Alloy plate– 5086 aluminum plate has higher strength than 5052 plate and 5083 plate and its mechanical properties vary significantly with hardening and temperature. It is not strengthened by heat treatment; instead, it becomes stronger due to strain hardening or cold working of the material. This alloy can be readily welded, retaining most of its mechanical strength. The good results with welding and good corrosion properties in seawater make Alloy 5086 extremely popular in marine applications. It is also easy to form, stamp and weld. 
5456 Aluminum Alloy plate – This alloy is primarily used in areas where high strength and better welding parameters are required in a marine vessel or other engineering applications. Alloy 5456 is stocked in tempers H116, H321; to spec ASTM B928. Tempers O, H112, H32; to spec ASTM B209 this alloy has higher tensile strength than other marine alloys such as 5083 or 5086, and good corrosion resistance in a sea water environment, but not always the formability and corrosion performance of some of the other alloys.
5454 Aluminum Alloy plate – This alloy is primarily used in areas where good formability is required, it is used in O, H112, H32, H34; to specification ASTM B209 Tempers and is an excellent choice for large pressure vessels and certain marine fabricated products. The formability is at its best in the soft 0 temper, but also sometimes used in H32 or H34 tempers too. However the strength and corrosion resistance are not always as good as other alloys, so as always a marine structural engineer should be consulted for each application.
5052 H32 Aluminum Alloy plate – A common alloy with good strength and weldability and it is easy to form and fabricate. However, not always considered a true marine alloy.
6061 T6 Aluminum Alloy plate – A heat treated alloy with higher strength used in many general engineering applications.However, again not considered a true marine alloy.
