Marine aluminum plate four principles

By zhangmenghao More Blogs by This Author

There are four principles for Marine aluminum alloy material selection:

rnrn

1. High specific strength and modulus. The structural strength and size of ships are closely related to the yield strength and elastic modulus of materials. Because the elastic modulus and density of aluminum alloys are roughly the same, the addition of alloyed elements also has little effect, so increasing the yield strength within a certain range is powerful to reduce the structure of ships. High strength aluminum alloys are generally difficult to have excellent corrosion resistance and weldability at the same time. Therefore, Marine aluminum alloys are generally medium strength, corrosion resistant and weldable alloys.

2. Excellent welding performance. At present, automatic argon arc welding method is mainly used in ships. Good weldability means that the crack tendency of aluminum alloy formed during welding is smaller, that is to say, aluminum alloy should have good welding crack resistance. The lost weldability cannot be restored by reheat treatment under shipbuilding conditions.

3. Excellent corrosion resistance. Ship structure how many harsh seawater medium and Marine environment, so corrosion resistance is one of the main signs of Marine alloys.

4. Aluminum alloy has good cold and hot forming performance. Due to the cold processing and hot processing in shipbuilding, Marine aluminum alloy must be easy to be processed and formed, without crack defects, and can still meet the requirements of strength and corrosion resistance after processing.

Marine Aluminum plate is Marine Grade Aluminum, which has strict material selection. Currently, Aluminum alloy products such as 5083, 5086, 5454, 5754 and 6061 are mostly used. In practical application, the advantage of Marine aluminum alloy is very obvious. Firstly, small specific gravity can reduce ship weight, save energy consumption and increase load; The second is good corrosion resistance, reduce the cost of oil, extend the service life; Third, welding, processing and forming good performance, conducive to later processing; After the aluminum waste is easy to recover, can be recycled, at the same time, do not burn, fire safety.
