Aluminum profiles for ships: Due to their low density, high strength, corrosion resistance, low processing costs, the use of aluminum alloy profiles in shipbuilding can improve speed extend service life, which can be said to be very cost-effective. Therefore, aluminum alloy profiles have great prospects in the shipbuilding industry, such as the use of deformed aluminum alloys for the sides, bottom outer plates, keels, decks, engine pedestals, other components of speedboats, sailboats, passenger ships, military boats, Other components such as pistons water pumps are mainly made of cast aluminum alloy, especially in the application of aircraft carriers. Due to the unique low density high strength characteristics of aluminum profiles, they play a crucial role in improving the tactical technical performance of aircraft carriers.
