Why Aluminium ?

Various metals can be used to build a boat hull, but the most common are usually aluminium and steel. Aluminium is an extremely strong material, which makes aluminum boats for carefree boats, with minimal maintenance, and a long boat season for the owner. A major advantage of aluminium hulls is that they do not necessarily need painting, except below the waterline or where fixtures and fittings are touching the hull surface. Bare aluminium forms an aluminium oxide coating on its surface that creates a barrier and prevents the metal from corroding. This results in a huge cost saving. 
There are several advantages of working with aluminium in superyacht construction projects. Not only is it light and strong, but it also has increased corrosion resistance and is flexible to work with. From a shipyard's point of view, it's therefore a great material to use; it can be cut with power tools, dressed with a router, filed and shaped easily.
Aluminium boats are lighter 30% than regular GRP boats, which means less fuel consumption and higher speeds achievements. Aluminium is known for its high strength to weight ratio than all materials used in boat building.
The alloy 5000 and 6000 series which are mainly used in boats building are known for their high strength and corrosion resistance, and yet have good elasticity to absorb impacts. Usually a good aluminium boat can live 30-40 years easily with regular checkup and little maintenance. Changing sacrificial anodes regularly and maintaining good electricity circuits with no leakage keeps the body in its original state.Our company use to aluminium 5083 H321.

5083 - H321 Sheet

Aluminium 5083 is known for exceptional performance in extreme environments. 5083 is highly resistant to attack by both seawater and industrial chemical environments. Alloy 5083 also retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.
