The Principles Of Marine Aluminum Material Selection:


First, there is a high specific strength and specific modulus, the ship's structural strength and size and material yield strength and elastic modulus are closely related, due to the elastic modulus and density of aluminum alloy is roughly the same, the addition of alloying elements also affect the slight , So within a certain range to improve the yield strength to reduce the ship structure is strong. High strength aluminum alloys are often difficult to have excellent corrosion resistance and weldability. Therefore, marine aluminum alloy is generally medium strength, corrosion resistant welding alloy;

Second, excellent welding performance. At present, the ship is mainly used in the automatic argon arc welding method, good weldability means that the formation of aluminum alloy welding cracks tend to be small, that is to say aluminum alloy to have a good welding crack resistance. Because the shipbuilding conditions can not be re-heat treatment to restore the loss of welding performance;

Third, it is excellent corrosion resistance, the ship structure how much harsh sea water and marine environment used, therefore, corrosion resistance is one of the main signs of marine alloys;

Fourth, the aluminum alloy has a good cold and hot forming performance, because the ship to be cold and processing and hot processing of a variety of processing, so the marine aluminum alloy must be easy to shape, without cracks, and processing can still meet the strength and Corrosion resistance requirements.
