Benefits: The major advantage of aluminum in ship building is its strength to density ratio. Aluminum has high tensile strength with less weight, which results in lowering the weight of the overall structure and thus reduce the fuel cost. When aluminum is exposed to air, a positive layer of oxide is formed on the surface which makes its corrosion resistant. Also, it is easily available in many standard forms as third most abundant metal, and can be transformed to all shapes
Disadvantages: i am seeking formal statements on what are some possible disadvantages of aluminum alloy as a replacement of steels in ship building.
