Advantages Of Aluminum Alloy In Marine Applications

2021.04.30

Aluminum alloy has the characteristics of small specific gravity and elastic modulus, corrosion resistance, weldability, easy processing, non-magnetic and good low-temperature performance. It has the following advantages when used in ships:

(1) Because of its small specific gravity, it can reduce the weight of the ship, reduce the single engine capacity, and increase the speed; it can reduce fuel consumption and save fuel; it can improve the length-to-width ratio of the ship, increase the stability, and make the ship easy to maneuver; You can also increase the load capacity and obtain additional profits.

(2) Because of its good corrosion resistance, it can reduce maintenance costs such as oiling, and can extend the service life (usually more than 20 years).

(3) Good processing and forming performance, easy to perform various forms of processing such as cutting, stamping, cold bending, forming and cutting, suitable for streamlining the hull; large and wide thin-walled profiles can be extruded, reducing the number of welds and The hull structure is rationalized and lightweight.

(4) The welding performance is good, and the welding can be carried out relatively easily.

(5) The modulus of elasticity is small, the ability to absorb impact stress is large, and it has greater safety.

(6) Aluminum scrap is easy to recycle and can be recycled.

(7) No low temperature brittleness, it is most suitable for low temperature equipment.

(8) Because it is non-magnetic, the compass is not affected; the all-aluminum boat can avoid mine attack and is suitable for minesweeper.

(9) No insect damage and dry deformation; no burning, safer in case of fire.
