Aluminum alloy plate is the main metal material in the world. The development of aluminum processing industry is supported by downstream real estate, automobile, railway transportation and power grid. According to the analysis, aluminum for transportation has become a new economic growth pole of the aluminum industry, and the growth rate of aluminum demand will exceed 8%.

Metal materials are used in the construction of transportation equipment, but steel products are easy to react with oxygen in the air, resulting in rust and oxidation. Therefore, aluminum alloy plate will be more and more widely used in transportation in the future because of its light weight and good oxidation and corrosion resistance.

At present, aluminum alloy is more and more widely used in shipbuilding industry. Marine grade aluminum sheets with good structural performance are used as ship hull, superstructure, various facilities, pipelines and appliances from small sampans and motor boats to 10000 ton giant ships, from civil to military, from high-speed hovercraft to Deep-water submarines, from fishing boats to marine mining ships.

The aluminum alloy medium and thick plate produced by Huawei Aluminum has the advantages of high strength, good extrusion, good weldability and good corrosion resistance. It is especially suitable for storage vessels of hull, underframe, frame and oil tank. While ensuring the strength of the hull, it reduces the weight of the hull, effectively saves energy and reduces the operation and maintenance cost.

The construction and working environment of the ship require that the materials should have good corrosion resistance, weldability, plasticity and certain properties such as tensile strength, yield strength, elongation and impact resistance. Aluminum alloys that meet these properties and are widely used in ships and have good effects include industrial pure aluminum, aluminum magnesium alloy and aluminum magnesium silicon alloy.
