Aluminum Marine Products, Thickness: 2 mm to 200 mm and above

Product Details

Featured products: 5083 Aluminium Alloy – Supplied in sheet marine grade tempers H116, H321, H323; to spec ASTM B928. Tempers O, H112, H32; to spec ASTM B209, and extrusion shapes in various tempers and specifications. This is an excellent marine environment corrosion resistant aluminum alloy, commonly used in Europe and Asia but becoming more frequently used in North America. It is primarily an alloy used for its corrosion resistant properties as it is especially good on inter granular corrosion resistance. Also, the tensile and yield strength is higher than 5086 alloy, so often these properties too are used by designers for their aluminum vessels. This alloy also has good welding capabilities for fabricating vessels. 5083 is also in inventory as H32 temper which is a good standard engineering alloy, but it does not have the corrosion resistance of the other special marine tempers.5086 Aluminium Alloy – Supplied in marine grade tempers H116, H321; to spec ASTM B928. Tempers O, H112, H32; to spec ASTM B209, and extrusion shapes in various tempers and specifications. This is an excellent marine environment corrosion resistant aluminum alloy, most commonly used in North America. It is also a marine grade alloy used for its corrosion resistant properties as it is also very good on inter granular corrosion. The benefits this alloy brings over standard alloys such as 5052 or 6061 is the corrosion resistance and better welding capabilities and good forming properties. 5086 is also in inventory as H32 temper which is a good standard engineering alloy, but it does not have the corrosion resistance of the other special marine tempers.5456 Aluminium Alloy – 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 Aluminium Alloy – 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 – Sheet & 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 Sheet & plate – A heat treated alloy with higher strength used in many general engineering applications.However, again not considered a true marine alloy.
