Marine grade 5083 and other aluminum alloy has been used in shipbuilding industry for nearly a hundred years. With the rapid development of shipbuilding industry at home and abroad, the lightweight of ships has been paid more and more attention. Due to the low density, high strength, high rigidity and corrosion resistance of aluminum (aluminum and Aluminum alloy has a low density, about 1/3 of steel, and has strong corrosion resistance to seawater), so the application effect of marine grade aluminum for ships on ships is very significant.

Marine grade 5083 aluminum for ships has the characteristics of small specific gravity and elastic modulus, corrosion resistance, weldability, easy processing, non-magnetic and good low temperature performance. It has the following advantages when used in ships:

(1),  Because of small specific gravity, marine grade aluminium 5083 can reduce the weight of the ship, can reduce the single engine capacity, can increase the speed; can reduce fuel consumption, save fuel; can improve the ship’s aspect ratio, increase stability, make the ship easier to maneuver.    

(2), Due to good corrosion resistance, aluminum 5083 can reduce maintenance costs such as oiling, can extend the service life. 

(3), Good processing and forming performance, marine grade aluminum is easy to perform various forms of processing such as cutting, stamping, cold bending, forming and cutting, suitable for streamlining the hull; large and wide thin-walled profiles can be extruded, reducing the number of welds and the hull structure is rationalized and lightweight.     

(4), Good welding performance, marine grade 5083 alloy can be welded more easily.   

(5), Small modulus of elasticity, high ability to absorb impact stress, higher safety.  

(6), Aluminum scrap is easy to recycle and can be recycled.
