6061 marine grade aluminum plate sheet has high strength, good processability and high corrosion resistance, The common alloy temper are 6061-o (annealed),, 6061 T6 (solutionized and artificially aged) and 6061-T651(solutionized, stress-relieved stretched and artificially aged).
6061 Aluminum plate is a precipitation-hardened aluminum alloy containing magnesium and silicon as its major alloying elements. 6061 aluminum plate is one of the most versatile of the heat-treatable alloys.  6061 is popular for its medium to high strength requirements, excellent corrosion resistance and good toughness.

Shipbuilding materials require a certain strength, weldability and high corrosion resistance. 6061 marine grade aluminum plate sheet is a very suitable shipbuilding material. It is commonly used for marine equipment such as yachts and other general-purpose vessels, general structural applications, and construction of pressure vessels.
