why is aluminium a good metal to use for the super structure top decks of. worships
Answers
Answer:
An excellent strength to weight ratio has made aluminium increasingly popular for shipbuilding in recent years. While its use in hull construction is largely confined to specific lengths and applications, aluminium is becoming increasingly popular for superstructures on many types of vessels (including tugs, tuna boats, research vessels, merchant ships, cruise liners and luxury mega yachts). There are a number of reasons for this trend:
Aluminium offers the same structural strength as steel but is up to 30% lighter. In addition, it is three times more elastic than steel, making it much more easily formed, which favours adaptation to different design shapes.
When it comes to steel, quality finishes, corrosion and oxidation are determining factors in how ships age, making aluminium the best option for designing and building naval superstructures for cruise liners and luxury mega yachts, where appearance is paramount and designs make use of attractive colours. Aluminium does not require maintenance since its own oxidation helps protect it.
Answer:
Aluminium is an excellent conductor of both heat and electricity. The great advantage of aluminium is that by weight, the conductivity of aluminium is around twice that of copper. This means that aluminium is now the most commonly used material in large power transmission lines.
