Application of aluminum alloy on ship:

1. First structure. The so-called "structure" refers to the strength of the main factors for the structural parts, such as the hull, large ship deck, etc..

2. Second structure. This kind of structure refers to the non force construction or construction of smaller stress, such as outfitting, fuel tank, water tank, storage room, watertight doors, windows, cover (ordinary rectangular windows, marine scuttle the ship, small boats and aluminum windows, roof hatch cover, mobile aluminum door, all kinds of ladder the passengers and the driving seat and the springboard, etc.), health settings, ventilation pipe, windshield, bracket, streamlined casing and a handle. Most of them are made of aluminium alloy materials such as 6063, 6082, 6061 and 3003.

3. Third structure. Such structures are mainly functional materials for the manufacture of cabin interiors and insulation and sound insulation materials. Aluminum alloy has good anodizing and coloring properties. After treatment, it has a bright appearance and a strong corrosion resistance. In addition, the foam aluminum plate is a good sound insulation material in the engine room of the ship.

Alloy: 6061, 6082, 5083, 5086
Temper: T4, T6, H111, H112, H116, H321
Certificate: BV /DNV /ABS/Lioyds

Normal marine aluminum profile types:

1. high 40--300mm symmetrical round head flat aluminum;

2. high 40--200mm asymmetrical round flat aluminum;

3. thickness 3--80mm, width 7.5---250mm flat aluminum;

4. height 70--400mm with rounded corner aluminum;

5. height 35--120mm reverse round head aluminum;

6.15mm*15mm---200*200mm equilateral aluminum;

7.20mm*15mm---200*120mm non equilateral aluminum;

8. flanges 25mm*45mm, grooved aluminum 40mm*250mm;

9.60*200*8/5, about 60mm*150*5/4 T type aluminum.

On ships, tubes are usually made of small diameter aluminum alloy tubes, while large diameter tubes are used for hull, superstructure, mast construction, support etc.., Commonly used pipe diameter 16mm---150mm, pipe wall thickness 3---8mm., in the pipe line for thickness selection, we should consider the strength, but also pay attention to the corrosive medium.
