5456 aluminum plate
The marine grade aluminum sheets price has a lot to do with their specifications, properties and technology levels. 5456 has slightly higher strength and stress corrosion sensitivity than 5083. But its machinability is not good in the annealed state. Moreover, the corrosion resistance of 5456 is not high, which can be saved by anodizing treatment, painting methods or layer coating of the surface. In this way 5456 can be applied to hulls and decks in marine building, or else it’s only used in river and lake ships and boats. Needless to say, the 5456 marine grade aluminium sheet price is higher than ordinary 5456 sheets.

Applications of 5456 aluminium alloy in shipbuilding
Surface-treated (anodizing, coating) 5456 aluminium is of marine grade. It’s made into hulls and decks of ships. Ordinary plain 5456 aluminium sheets are applied to boats (cargo boats, rowboats, electric boats, pedal boats, pleasure boats) in fresh water.
5456 marine grade aluminium sheet price
5456 marine aluminum sheet prices higher than those of common 5456 sheets for fresh water boats. Specific prices can only be obtained by contacting us, for they fluctuate day to day.
