Mae llongau aloi alwminiwm wedi'u defnyddio mewn diwydiant ers amser maith ac wedi cyflawni canlyniadau rhagorol. Mae cychod cyflym aloi alwminiwm wedi dod yn brif ddull cludo ar gyfer afonydd mewndirol, mordwyo alltraeth, patrolau gwaith, a physgota hamdden. Mae aloi alwminiwm yn cael ei ffafrio gan bobl oherwydd ei bwysau ysgafn, ei ffurfiant hawdd a'i ymwrthedd cyrydiad. Ar ôl mwy na chan mlynedd o ymchwil a datblygu, mae aloi alwminiwm wedi'i ddefnyddio'n helaeth mewn llongau ac wedi dod yn ddeunydd addawol yn y diwydiant adeiladu llongau.
1. Recyclable: Aluminum alloy can be recycled as a metal material. 2. Durable and long life: The ship inspection stipulates that the effective life of the aluminum alloy boat is 30 years3. Impact resistance: The impact resistance of aluminum alloy boats is stronger than that of FRP boats. As the service life of ships increases, this will become more and more obvious. Aluminum alloy has great advantages in impact resistance and corrosion resistance. 4. Quick repairability: the aluminum alloy hull can quickly recover after collision. If the hull does not leak after the impact, only a simple welding repair is needed to level the outer plate. If the hull shell collides and leaks, only need to re-cut and weld according to the size of the leak. The quality of the repaired hull is the same as that of the new hull, and the advantages of quick repair of the aluminum alloy hull are particularly obvious. 5. Light weight and fast speed: The weight of aluminum alloy hull is much lighter than that of glass fiber reinforced plastic hull and steel hull, but the strength is very good and will not affect the net load of the hull, thus greatly improving the speed and fuel economy of the ship.
