Firstly, aluminum plate means aluminum material which has the thickness of above 0.2 mm and under 500 mm, the length between 200 mm to 16 m

.

Then 20mm thick aluminum plate means the thickness of this kind of aluminum plate is 20 mm, the thickness of aluminum plate is higher then that of aluminum sheet.

And to aluminum plate, it has many models from 1000 series to 8000 series with different alloy content and physical, chemical performance. The common models are 1060, 1050, 1100, 3003, 5052, 5083, 6061, 8011 aluminum plate and so on. Aluminum plate have widely application area such as lighting lamp , solar reflected, building exterior, interior decoration, ceiling, metope, furniture, cabinets, elevator, signs, nameplate, luggage, automotive interior and exterior decoration, indoor decorations, frame, household appliances: refrigerators, microwave ovens, audio equipment, aerospace and military aspects, satellites, machinery parts processing, mold manufacturing, chemical thermal insulation pipe coating.

Aluminium plate 20 mm ships have a clear advantage over steel ships with regards to total ownership costs. This is due to the fact that aluminium ships are lighter and use less fuel than steel ships. Aluminium ships also do not incur lifecycle maintenance costs associated with painting, and because they are generally smaller, they require less manning. And when an aluminium vessel reaches the end of its life span, it continues to provide significant benefits as a result of its high recycling value.

Aluminium alloy sheet is used not only in construction of tankers and big ships but also in yachts, motor boats, cutters as well as underwater craft. Most of sporting boats are built from aluminium, from keel to mast, which gives them a speed advantage, while high capacity vessels are built from steel. Nevertheless, the superstructure and other auxiliary equipment is made from aluminium to save weight and increase the cargo carrying capacity.

With all the existing technologies and methods available for aluminium shipbuilding, Aluminum Brazing Sheet plate has the potential to replace steel in the future as the main ship construction material. The use of aluminium alloys will especially grow in smaller ships and yachts while the long ships and tankers (over 130 m) will continue to be dominated by steel. All in all, the further about aluminium plate for ship building future in shipbuilding is bright.

5083 marine aluminium sheet 20mm thick is popular in ship building, because of its properties:

1,With excellent corrosion resistance and weldability.

2,With welded structured requiring

3,It can be anodized inreased corrsion resistance.

4,Size: Thickness: 0.15-5.00mm(Tolorance±0.02mm) Width:200-1600mm(Tolorance±1mm) Length:500-1500mm(Tolorance±1mm)
