What aluminum plate grade should use for marine

What is the reason that so many of today’s best performing vessels, large and small, are constructed from marine grade aluminium.

The 5083 aluminum alloy provides the exceptional strength, workability and corrosion resistance that marine applications require, aluminium has been the material of choice for forward-looking designers wherever durability, economy of operation and construction, responsiveness or sheer speed are priorities.

Grade 5083 aluminum plate has the highest strength of all of the non heat treatable alloys, although it is not as strong or as hard as the more common grade 6082.

Because the performance is as important in the yard as it is on the water. You want high performance, user-friendly materials that give you the freedom to express your vision. Structural efficiency. Unimpeachable quality. And genuine versatility.

Grade 5083 aluminum is primarily available in plate form, and is most commonly available in O condition.

5083 Aluminium is also known by the following designations:

GM41

A95083

A1 MG4.5Mn

A1mg4.5 Mn0.7

Corrosion resistance

Grade 5083 aluminium has truly excellent resistance to both chemical and atmospheric attack. 5083 aluminium performs particularly well in sea water / salt water and for this reason is often referred to as a marine grade of aluminium.

Welding

Grade 5083 Aluminium has excellent weldability, and it also retains most of its strength after wielding. Please be aware that grade 5083 aluminium is not suitable for working in temperatures over 65 degrees C.

Machining

Grade 5083-O Aluminium plate is not recommended for machining. Where machining is required, grade 6082 is usually a more suitable option.

Cold working / forming

Grade 5083-O is suitable for bending, folding and cold working.

Aluminium Alloy 5083 is capable of being bent cold through an angle of 90 degrees around a pin having a radius equal to N times the thickness (t) of the sheet without cracking.

5083 Aluminum Sheet & Plate has exceptional thermal conductivity and higher strength than 5052 . It is highly resistant to attack by seawater and industrial chemicals and is very suitable for welding.
