Mengapa aluminium digunakan dalam pembuatan kapal?

  1. Ringan: Aluminium jauh lebih ringan dibandingkan baja, menjadikannya pilihan ideal untuk pembuatan kapal. Dengan menggunakan aluminium sebagai pengganti baja, berat keseluruhan kapal dapat dikurangi, menghasilkan peningkatan efisiensi bahan bakar dan kapasitas muatan yang lebih tinggi. Hal ini sangat penting untuk kapal seperti feri, yachts, and high-speed crafts.
  2. Ketahanan Korosi: Aluminum has excellent corrosion resistance, especially in marine environments where ships are exposed to saltwater. Unlike steel, which can rust and corrode, aluminum forms a protective oxide layer on its surface, providing inherent resistance to corrosion. This reduces maintenance requirements and increases the longevity of the ship.
  3. High Strength-to-Weight Ratio: Despite being lightweight, aluminum offers high strength. It possesses a favorable strength-to-weight ratio, meaning it provides good structural integrity while keeping the weight of the ship low. This is crucial for maintaining the structural integrity and stability of the vessel, especially in rough seas.
  4. Ease of Fabrication: Aluminum is a highly malleable and easily workable material. It can be formed, lasan, and joined using various techniques, allowing for flexibility in ship design and construction. This ease of fabrication makes aluminum a preferred choice for building complex ship structures and components.
  5. Recyclability: Aluminum is highly recyclable, and the recycling process requires significantly less energy compared to the production of primary aluminum. This aligns with sustainability goals and environmental considerations, making aluminum an attractive option for shipbuilders looking for eco-friendly solutions.
