Because of the low density, 3/1 of steel, and good molding, processing performance, the aluminum plate is widely used for shipbuilding, especially some friction stir welding (FSW) performance; Strong corrosion resistance; Without the brittleness at low temperature, the strength and plasticity (elongation, compression ratio, toughness) are balanced with lower temperature to rise, but in a negative or work under the lower temperature under 200 ℃; It is highly recyclable and has high recovery rate in structural metal materials.
Three application of aluminum pate for shipbuilding

1. Stress structure with strength as the main factor, such as hull, large ship deck room, ship bridge, missile launcher, electromagnetic gun rail, etc. The electromagnetic gun was mounted on the world's larger aircraft carrier, the ford, which was launched in October 2013. It had an aluminum track and was also used in the test. The aluminum bomb receives in the electromagnetic gun Powered by 10680KJ energy, it flew out of orbit at the speed of 7Ma (Mach) and hit an overland target 360km away under the guidance of the global positioning system.

2. This Non-force or stress smaller components, such as various fitting-out pieces, such as, fuel tank, water tank, storage tank, aluminum door, window, cover (Marine ordinary rectangular window, Marine string, small boat aluminium window, aluminium window, aluminum shutters, all kinds of hatch cover, the rectangle window, portable aluminum door, Marine weathertight single aluminum door, cabin door on an empty stomach, all kinds of elevator and the springboard, passenger and driving seat and sofa, etc.), sanitation, pipes, ventilation, wind deflector, stents, streamlined cover and handle.They are mostly made of aluminum plate, such as 6063, 6082 and 3003 aluminum plate.
3. Functional material, used for making decoration parts and insulation and sound insulation materials of warehouse interior department. Aluminum and aluminum alloy have good performance of anodizing coloring. After this treatment, the appearance is bright and the corrosion resistance is quite strong .The Japan maritime association and other national shipbuilding departments have been approved as ship interior decorative boards, as well as window and window materials.Materials such as fiberglass and wood used in the past can be used instead.

The aluminum plate for shipbuilding are mainly marine grade aluminum 5052, marine grade aluminum 5083,  marine grade aluminum 5086 and marine grade aluminum 6063, with DNV, CCS, BV certificate.
