Marine grade aluminum is aluminum alloys which can be used in shipbuilding industry with high corrosion resistance characters. Besides, Marine grade aluminum alloy as a non-heat treatable grade offers a high level of strength. Its fatigue strength is greater than the majority of other aluminum grades. In addition, it offers good resistance to Marine atmosphere and saltwater corrosion.
With the rapid development of shipbuilding industry at home and abroad, more and more attention has been paid to the lightweight of ships.
Marine grade aluminum alloy has the following advantages:
(1) due to its small specific gravity, it can reduce the ship's weight, reduce the single engine capacity, and increase the speed;Can reduce fuel consumption, fuel economy;Can improve the ship's aspect ratio, increase the stability, make the ship easy to operate;Can also increase the load, get extra profit.
(2) the service life can be extended (usually more than 20 years) due to the good corrosion resistance, which can reduce the maintenance cost such as oil coating.
(3) good processing and forming performance, easy to cut, stamping, cold bending, forming and cutting and other forms of processing, suitable for the streamline of the hull;Can be extruded out of large wide thin-walled profiles, reduce the number of welding seams and make the hull structure reasonable and lightweight.
(4) good welding performance, can be easily welded.
(5) the elastic modulus is small, the ability to absorb shock stress is large, and the safety is large.
(6) aluminum waste is easy to recover and can be recycled.
(7) no low temperature brittleness, the most suitable for low temperature equipment.
(8) due to non-magnetic, the compass is not affected;All aluminum ships can avoid mine attacks and are suitable for use as minesweepers.
(9) no insect pests and dry deformation;Do not burn, in case of fire safer.
From the point of view of ship designers, ships made of aluminum alloy can achieve higher speed and longer service life. These advantages of aluminum alloy make it develop rapidly in the application of ships
