5052

This alloy is remarkably resistant to seawater corrosion. Its medium to high strength alloy make-up allow for good cold formability and exceptional
weldability. Magnesium is the major alloying element for 5052.  In the marine industry, it is the primary material for boat hulls and cargo tanks.

5083

Of all non-heat treatable alloys, this has the highest strength.  5083 is resistant to stress, cracking and exfoliation attack

under in marine corrosive conditions. It has a low density and excellent thermal conductivity. It is used across many industries, but primarily shipbuilding.

5086

This alloy shows great results when welded, retaining most of its strength.  This factor, along with its corrosion resistance in seawater make it a very popular material choice for the marine industry.  5086 is used extensively for hulls and vessel gangways.

5456

Alloy 5456 is used as a standard application in welded deckhouse construction of destroyers. It is a preferred material because of the 40-45% weight reduction with no loss of stability.  It can be hot worked and has good strength.

6061

This alloy has good weldability and valuable mechanical properties.  It is used most often because of these qualities and its strength and workability.  It is used most often in deckhouse structures, small boats, and bulk-heads.

Designers are now taking a proactive approach to corrosion control early in the design process.  Instead of facing the extended cost and safety issues associated with material replacement, up-front plans for protection now routinely include the use of marine grade aluminum.
